These results are consistent with the broken fourfold;rotational symmetry in the hidden-order phase, which can modify the;interband scattering in an asymmetric manner. We also extend our;measurements down to 0.7 K, which results in the observation of;cyclotron resonance in the superconducting state, where novel effects of;vortex dynamics may enter.

To describe collective plasma;excitations in the 2DEG, we develop a generalized transmission line;theoretical formalism consistent with the plasma hydrodynamic model. We;then apply this formalism to analyze the plasmonic spectra of 2DEG;systems with steplike periodic changes of electron density, gate;screening, or both. We show that in a periodically modulated 2DEG, a;plasmonic crystal is formed, and we derive closed-form analytical;expressions describing its energy band spectrum for both infinite and;finite size crystals. Our results demonstrate a nonmonotonic dependence;of the plasmonic band gap width on the electron density modulation. At;so-called transparency points, where the plasmon propagates through the;periodic 2DEG in a resonant manner, the plasmonic band gaps vanish. In;semi-infinite plasmonic crystals, we demonstrate the formation of;plasmonic Tamm states and analytically derive their energy dispersion;and spatial localization. Finally, we present detailed numerical;analysis of the plasmonic band structure of a finite four-period;plasmonic crystal terminated either by an ohmic contact or by an;infinite barrier on each side. We trace the evolution of the plasmonic;band spectrum, including the Tamm states, with changing electron density;modulation and analyze the boundary conditions necessary for formation;of the Tamm states. We also analyze interaction between the Tamm states;formed at the opposite edges of the short length plasmonic crystal. The;validity of our theoretical approach was confirmed in experimental;studies of plasmonic crystals in short, modulated plasmonic cavities;[Dyer et al., Phys. Rev.

The measured 1/f;noise around the magnetic hysteresis loops of the free layer indicates;that the main origin of the 1/f noise is the magnetic fluctuation, which;is discussed in terms of a fluctuation-dissipation relation. Random;telegraph noise (RTN) is observed to be symmetrically enhanced in the;hysteresis loop with regard to the two magnetic configurations. We found;that this enhancement is caused by the fluctuation between two magnetic;states in the free layer. Although the 1/f noise is almost independent;of the magnetic configuration, the RTN is enhanced in the antiparallel;configuration.

The problem is;formulated in terms of finite-temperature DFT where the discontinuity in;the xc potential emerges naturally in the limit of zero temperature. A;simple parametrization is suggested for the xc potential of the uniform;one-dimensional (1D) Hubbard model at finite temperature which is;obtained from the solution of the thermodynamic Bethe ansatz. The;feasibility of the numerical scheme is demonstrated by application to a;model of fermionic atoms in a harmonic trap. The corresponding density;profile exhibits a plateau of integer occupation at low temperatures;which melts away for higher temperatures.

Regrettably, themechanism(s);responsible for the superconductivity has yet to be unequivocally;identified. High pressure is an important variable since its application;moderates the pairing interaction. Thus far, the LnFePO (Ln = La, Pr,;Nd, Sm, Gd) family of superconductors has received relatively little;attention. Early high-pressure studies on LaFePO found that T-c;initially increased with pressure before passing through a maximum at;higher pressures. The present studies on both polycrystalline and;single-crystalline LaFePO, PrFePO, and NdFePO utilize the most;hydrostatic pressure medium available, i.e., dense He.

A magnetic-field-induced spin-flop;transition was seen below T-N when the applied B is parallel to the c;axis, the magnetic easy axis, together with a huge frustration parameter;f = theta(W)/T-N. A pronounced Schottky-type anomaly in specific heat;was also found around 160 K, which could be attributed to the;crystalline electric field effect with the excitation energies being;fitted to Delta(1) = 325 K and Delta(2) = 520 K, respectively. Moreover,;the in-plane resistivity anisotropy and low-temperature x-ray;diffractions suggest that this compound is a rare example exhibiting a;possible structure distortion induced by the 4f-electron magnetic;frustration.

We present evidence that the high-temperature second-order;ferromagnetic transition can be coupled with the low-temperature;first-order crystallographic transformation into a single first-order;magnetic-crystallographic transformation using a magnetic field and;hydrostatic pressure as tuning parameters. The effect of pressure on the;Griffiths-like phase is reported and analyzed in the framework of the;complex competition between the interslab and intraslab magnetic;interactions.;Magen, Cesar/A-2825-2013; Morellon, Luis/K-6922-2014; Marcano Aguado, Noelia/F-9446-2010;

To describe collective plasma;excitations in the 2DEG, we develop a generalized transmission line;theoretical formalism consistent with the plasma hydrodynamic model. We;then apply this formalism to analyze the plasmonic spectra of 2DEG;systems with steplike periodic changes of electron density, gate;screening, or both. We show that in a periodically modulated 2DEG, a;plasmonic crystal is formed, and we derive closed-form analytical;expressions describing its energy band spectrum for both infinite and;finite size crystals. Our results demonstrate a nonmonotonic dependence;of the plasmonic band gap width on the electron density modulation. At;so-called transparency points, where the plasmon propagates through the;periodic 2DEG in a resonant manner, the plasmonic band gaps vanish. In;semi-infinite plasmonic crystals, we demonstrate the formation of;plasmonic Tamm states and analytically derive their energy dispersion;and spatial localization. Finally, we present detailed numerical;analysis of the plasmonic band structure of a finite four-period;plasmonic crystal terminated either by an ohmic contact or by an;infinite barrier on each side. We trace the evolution of the plasmonic;band spectrum, including the Tamm states, with changing electron density;modulation and analyze the boundary conditions necessary for formation;of the Tamm states. We also analyze interaction between the Tamm states;formed at the opposite edges of the short length plasmonic crystal. The;validity of our theoretical approach was confirmed in experimental;studies of plasmonic crystals in short, modulated plasmonic cavities;[Dyer et al., Phys. Rev. Lett. 109, 126803 (2012)], which demonstrated;excellent quantitative agreement between theory and experiment.;DOI:10.1103/PhysRevB.86.235316;9;0;0;0;9;1098-0121;WOS:000312833200005;;;J;Arakawa, Tomonori;Tanaka, Takahiro;Chida, Kensaku;Matsuo, Sadashige;Nishihara, Yoshitaka;Chiba, Daichi;Kobayashi, Kensuke;Ono, Teruo;Fukushima, Akio;Yuasa, Shinji;Low-frequency and shot noises in CoFeB/MgO/CoFeB magnetic tunneling;junctions;PHYSICAL REVIEW B;86;22;224423;10.1103/PhysRevB.86.224423;DEC 28 2012;2012;The low-frequency and shot noises in spin-valve CoFeB/MgO/CoFeB magnetic;tunneling junctions were studied at low temperature. The measured 1/f;noise around the magnetic hysteresis loops of the free layer indicates;that the main origin of the 1/f noise is the magnetic fluctuation, which;is discussed in terms of a fluctuation-dissipation relation. Random;telegraph noise (RTN) is observed to be symmetrically enhanced in the;hysteresis loop with regard to the two magnetic configurations. We found;that this enhancement is caused by the fluctuation between two magnetic;states in the free layer. Although the 1/f noise is almost independent;of the magnetic configuration, the RTN is enhanced in the antiparallel;configuration. These findings indicate the presence of spin-dependent;activation of RTN. Shot noise reveals the spin-dependent coherent;tunneling process via a crystalline MgO barrier.

In particular, we;probe domain walls nucleated in the free layer of the spin-valves, which;are then pinned in the devices. We have determined both the;field-current state diagrams for the domain-wall state and the thermally;activated dynamics of the nucleation and depinning processes. We show;that the nucleation process is well-described by a modified Neel-Brown;model taking into account the spin-transfer torque, whereas the;depinning process is independent of the current. This is confirmed by an;analytical calculation which shows that spin-torques have no effect on;the Arrhenius escape rate associated with thermally activated domain;wall depinning in this geometry. Furthermore, micromagnetic simulations;indicate that spin-transfer only weakly affects the domain wall motion,;but instead modifies the inner domain wall structure.

This is possible owing;to the extreme sensitivity of the o/afm (for T <= T-s,T-N) and;superconducting (T <= T-c) states against variation of pressure,;disclosing pressure coefficients of dT(s,N)/dP = -(1100 +/- 50) K/GPa;and dT(c)/dP = -(60 +/- 3) K/GPa, respectively. Systematic;investigations of the various phase transitions and ground states via;pressure tuning revealed no coexistence of bulk superconductivity (sc);with the o/afm state which we link to the strongly first-order character;of the corresponding structural/magnetic transition in this compound.;Our results, together with literature results, indicate that preserving;fluctuations associated with the o/afm transition to low enough;temperatures is vital for sc to form.

An objective structure (OS) is one for which a;group of atoms, called a "fundamental domain" (FD), is repeated using;specific rules of translation and rotation to build a more complex;structure. An objective Cauchy-Born rule defines the kinematics of the;OS atoms in terms of a set of symmetry parameters and the positions of;the FD atoms. The computational advantage lies in the capability of;representing a large system of atoms through a small set of symmetry;parameters and FD atom positions.

OQC simulations are performed for uniform and;nonuniform bending for two different orientations (nanobeam axis;oriented along [111] and [100]) and compared with elastica results.

We compute the entanglement entropy;and the entanglement spectra using a variety of partitions or "cuts" of;the Hilbert space, including two distinct real-space cuts and a;momentum-space cut. Our results show that the Kugel-Khomski model;possesses a number of new features not previously encountered in studies;of the entanglement spectra. Notably, we find robust gaps in the;entanglement spectra for both gapped and gapless phases with the orbital;partition, and show these are not connected to each other. The counting;of the low-lying entanglement eigenvalues shows that the "virtual edge";picture, which equates the low-energy Hamiltonian of a virtual edge,;here one gapless leg of a two-leg ladder, to the "low-energy";entanglement Hamiltonian, breaks down for this model, even though the;equivalence has been shown to hold for a similar cut in a large class of;closely related models. In addition, we show that a momentum space cut;in the gapless phase leads to qualitative differences in the;entanglement spectrum when compared with the same cut in the gapless;spin-1/2 Heisenberg spin chain. We emphasize the new information content;in the entanglement spectra compared to the entanglement entropy, and;using quantum entanglement, we present a refined phase diagram of the;model. Using analytical arguments, exploiting various symmetries of the;model, and applying arguments of adiabatic continuity from two exactly;solvable points of the model, we are also able to prove several results;regarding the structure of the low-lying entanglement eigenvalues.

The;method that we present is able to take into account the effects of the;strong disorder-induced carrier density inhomogeneities that;characterize the ground state of the surfaces of 3DTIs, especially at;low doping, as recently shown experimentally. Due to the inhomogeneous;nature of the carrier density landscape, standard theoretical techniques;based on ensemble averaging over disorder assuming a spatially uniform;average carrier density are inadequate.

The procedure is applied;to the Al-Zr system because of its importance in the development of high;strength Al-Li alloys and of bulk metallic glasses. Cohesive energies of;the studied condensed phases of the Al-Zr system (the liquid phase, the;fcc solid solution, and various orthorhombic stoichiometric compounds);are calculated using the modified embedded atom model (MEAM) in the;second-nearest-neighbor formalism (2NN). The Al-Zr MEAM-2NN potential is;parameterized in this work using ab initio and experimental data found;in the literature for the AlZr3-L1(2) structure, while its predictive;ability is confirmed for several other solid structures and for the;liquid phase. The thermodynamic integration (TI) method is implemented;in a general MC algorithm in order to evaluate the absolute Gibbs energy;of the liquid and the fcc solutions. The entropy of mixing calculated;from the TI method, combined to the enthalpy of mixing and the heat;capacity data generated from MD/MC simulations performed in the;isobaric-isothermal/canonical (NPT/NVT) ensembles are used to;parameterize the Gibbs energy function of all the condensed phases in;the Al-rich side of the Al-Zr system in a CALculation of PHAse Diagrams;(CALPHAD) approach. The modified quasichemical model in the pair;approximation (MQMPA) and the cluster variation method (CVM) in the;tetrahedron approximation are used to define the Gibbs energy of the;liquid and the fcc solid solution respectively for their entire range of;composition. Thermodynamic and structural data generated from our MD/MC;simulations are used as input data to parameterize these thermodynamic;models. A detailed analysis of the validity and transferability of the;Al-Zr MEAM-2NN potential is presented throughout our work by comparing;the predicted properties obtained from this formalism with available ab;initio and experimental data for both liquid and solid phases.

We;have succeeded in substituting Fe for Al in beta-YbAlB4 as well as the;polymorphous compound alpha-YbAlB4, which in contrast has a heavy;Fermi-liquid ground state. Full structure determination by;single-crystal x-ray diffraction confirmed no change in crystal;structure for both alpha- and beta-YbAlB4, in addition to volume;contraction with Fe substitution. Our measurements of the magnetization;and specific heat indicate that both alpha-YbAl0.93Fe0.07B4 and;beta-YbAl0.94Fe0.06B4 exhibit a magnetic order, most likely of a canted;antiferromagnetic type, at 7 similar to 9 K. The increase in the entropy;as well as the decrease in the antiferromagnetic Weiss temperature with;the Fe substitution in both systems indicates that the chemical pressure;due to the Fe substitution suppresses the Kondo temperature and induces;the magnetism.

Via the;Keldysh perturbative approach, we find that the effects of the;single-particle and the two-particle scattering processes on the current;noise depend sensitively on the Luttinger liquid parameter. Moreover,;the Fano factors for the auto-and cross correlations of the currents in;the terminals are distinct from the ones for tunneling between the;chiral edge states in the quantum Hall liquid.

[Science 336,;1003 (2012)] claiming the likely observation of the Majorana mode in a;semiconductor-superconductor hybrid structure, we study theoretically;the dependence of the zero-bias conductance peak associated with the;zero-energy Majorana mode in the topological superconducting phase as a;function of temperature, tunnel barrier potential, and a magnetic field;tilted from the direction of the wire for realistic wires of finite;lengths. We find that higher temperatures and tunnel barriers as well as;a large magnetic field in the direction transverse to the wire length;could very strongly suppress the zero- bias conductance peak as observed;in recent experiments.

To describe collective plasma;excitations in the 2DEG, we develop a generalized transmission line;theoretical formalism consistent with the plasma hydrodynamic model. We;then apply this formalism to analyze the plasmonic spectra of 2DEG;systems with steplike periodic changes of electron density, gate;screening, or both. We show that in a periodically modulated 2DEG, a;plasmonic crystal is formed, and we derive closed-form analytical;expressions describing its energy band spectrum for both infinite and;finite size crystals. Our results demonstrate a nonmonotonic dependence;of the plasmonic band gap width on the electron density modulation. At;so-called transparency points, where the plasmon propagates through the;periodic 2DEG in a resonant manner, the plasmonic band gaps vanish. In;semi-infinite plasmonic crystals, we demonstrate the formation of;plasmonic Tamm states and analytically derive their energy dispersion;and spatial localization. Finally, we present detailed numerical;analysis of the plasmonic band structure of a finite four-period;plasmonic crystal terminated either by an ohmic contact or by an;infinite barrier on each side. We trace the evolution of the plasmonic;band spectrum, including the Tamm states, with changing electron density;modulation and analyze the boundary conditions necessary for formation;of the Tamm states. We also analyze interaction between the Tamm states;formed at the opposite edges of the short length plasmonic crystal. The;validity of our theoretical approach was confirmed in experimental;studies of plasmonic crystals in short, modulated plasmonic cavities;[Dyer et al., Phys. Rev. Lett. 109, 126803 (2012)], which demonstrated;excellent quantitative agreement between theory and experiment.;DOI:10.1103/PhysRevB.86.235316;9;0;0;0;9;1098-0121;WOS:000312833200005;;;J;Arakawa, Tomonori;Tanaka, Takahiro;Chida, Kensaku;Matsuo, Sadashige;Nishihara, Yoshitaka;Chiba, Daichi;Kobayashi, Kensuke;Ono, Teruo;Fukushima, Akio;Yuasa, Shinji;Low-frequency and shot noises in CoFeB/MgO/CoFeB magnetic tunneling;junctions;PHYSICAL REVIEW B;86;22;224423;10.1103/PhysRevB.86.224423;DEC 28 2012;2012;The low-frequency and shot noises in spin-valve CoFeB/MgO/CoFeB magnetic;tunneling junctions were studied at low temperature. The measured 1/f;noise around the magnetic hysteresis loops of the free layer indicates;that the main origin of the 1/f noise is the magnetic fluctuation, which;is discussed in terms of a fluctuation-dissipation relation. Random;telegraph noise (RTN) is observed to be symmetrically enhanced in the;hysteresis loop with regard to the two magnetic configurations. We found;that this enhancement is caused by the fluctuation between two magnetic;states in the free layer.

Here, simulation parameters are derived;from a series of measurements using a self-consistent "building-blocks";approach, starting from data on the simplest systems. We found that site;energies show disorder and that correlations in the site energies and a;distribution of deep traps must be included in order to reproduce;measured charge mobility-field curves at low charge densities in bulk;PFB and F8BT. The parameter set from the mobility-field curves;reproduces the unipolar current in single layers of PFB and F8BT and;allows us to deduce charge injection barriers. Finally, by combining;these disorder descriptions and injection barriers with an optical;model, the external quantum efficiency and current densities of blend;and bilayer organic PV devices can be successfully reproduced across a;voltage range encompassing reverse and forward bias, with the;recombination rate the only parameter to be fitted, found to be 1 x;10(7) s(-1).

We;have also used the same model to predict the band-gap wavelengths of;over 30 more superlattices, measured by photoluminescence spectroscopy.;The maximum error is 0.6 mu m, which corresponds to an uncertainty of;less than 0.4 ML in layer width.

By eliminating all terms;from the Hamiltonian, the energy contribution of which is less than the;error due to the uncertainty in layer widths, the number of unknown;fitting parameters has been reduced to six: two Luttinger parameters,;three interface parameters, and the valence band offset. The remaining;four Luttinger parameters are not independent and are determined from;the two independent ones. Our set of Luttinger parameters is close to;that reported by Lawaetz [Phys. Rev.

The interface parameters are diagonal;and have values of D-S = 3 eV angstrom, D-X = 1.3 eV angstrom, and D-Z =;1.1 eV angstrom at 77 K. The off-diagonal interface parameters alpha and;beta are too small to be fitted with any accuracy and have negligible;effect on the unpolarized photoabsorption spectra.

The thermodynamic integration (TI) method is implemented;in a general MC algorithm in order to evaluate the absolute Gibbs energy;of the liquid and the fcc solutions.

The Higgs and non-Abelian Coulomb phases;exhibit multiple ground states on boundaryless spatial three-manifolds;with nontrivial first homology, while the Abelian Coulomb phase has a;unique ground state. The ground-state degeneracy receives an additional;contribution on manifolds with boundary due to the induced boundary;Chern-Simons term.

From;this new series, the previously formulated RT-RG equations are obtained;naturally.

The crossover between the two regimes is;found to coincide with the boundary of the normal-state pseudogap,;providing further evidence of the unconventional nature of;superconductivity in the pseudogap regime. However, the absence, in the;strongly correlated but nonsuperconducting state, of discernibly;nonlinear response to an applied pairing field suggests that resonating;valence bond physics is not the origin of the kinetic-energy driven;superconductivity.

The alloy band gap energies determined from;PL maxima are described with a bowing parameter of 0.87 eV, which is;significantly larger than measured for InAsSb in earlier work.

Currently,;crystalline defects such as dislocations limit the performance of these;materials. Atomistic simulations are a powerful method for exploring;crystalline defects at a resolution unattainable by experimental;techniques. To enable accurate atomistic simulations of defects in the;Cd-Zn-Te systems, we develop a full Cd-Zn-Te ternary bond-order;potential. This Cd-Zn-Te potential has numerous unique advantages over;other potential formulations: (1) It is analytically derived from;quantum mechanical theories and is therefore more likely to be;transferable to environments that are not explicitly tested. (2) A;variety of elemental and compound configurations (with coordination;varying from 1 to 12) including small clusters, bulk lattices, defects,;and surfaces are explicitly considered during parameterization. As a;result, the potential captures structural and property trends close to;those seen in experiments and quantum mechanical calculations and;provides a good description of melting temperature, defect;characteristics, and surface reconstructions. (3) Most importantly, this;potential is validated to correctly predict the crystalline growth of;the ground-state structures for Cd, Zn, Te elements as well as CdTe,;ZnTe, and Cd1-xZnxTe compounds during highly challenging molecular;dynamics vapor deposition simulations.

In addition, as the injection-coupling strength;increases, the gain peak value is enhanced and the spectrum is slightly;broadened, while an increase of the extraction-coupling strength reduces;the gain peak value and broadens the gain spectrum.

Two cases are considered. The first is the;counterflowing (Vinen) turbulence, where the vortex lines are;disordered, and the evolution of quantity L(t) obeys the Vinen equation.;The second case is the fluctuations of the VLD in a single vortex;bundle, which develops inside the domain of the concentrated;normal-fluid vorticity. The dynamics of the vortex bundle is described;by the Hall-Vinen-Bekarevich-Khalatnikov (HVBK) equations. The latter;case is of special interest, because the set of the quantum vortex;bundles is believed to mimic classical hydrodynamic turbulence. In;steady states the VLD is related to the normal velocity as L = (rho;gamma/rho(s))(2)upsilon(2)(n) for the Vinen case. In the vortex bundle;case, which appears inside the domain of a concentrated vorticity of;normal fluid, the stationary quantity L can be found from the matching;of velocities and is described by L = vertical bar del x v(n)vertical;bar/kappa. In nonstationary situations, and particularly in the;fluctuating turbulent flow, there is a retardation between the;instantaneous value of the normal velocity and the quantity L. This;retardation tends to decrease in accordance with the inner dynamics,;which has a relaxation character. In both cases, the relaxation dynamics;of the VLD is related to fluctuations of the relative velocity. However,;for the Vinen case the rate of temporal change for L(t) is directly;dependent upon delta v(ns), whereas for HVBK dynamics it depends on del;x delta v(ns). Therefore, for the disordered case the spectrum coincides with the spectrum omega(-5/3).

Here we examine;possible high-T, P polymorphism in Ta with complementary DFT-based model;generalized pseudopotential theory (MGPT) multi-ion interatomic;potentials, which allow accurate treatment of much larger system sizes;(up to similar to 80000 atoms). We focus on candidate bcc, A15, fcc,;hcp, and hex-omega phases for the high-T, P phase diagram to 420 GPa,;studying the mechanical and relative thermodynamic stability of these;phases for both small and large computational cells. Our MGPT potentials;fully capture the T = 0 DFT energetics of these phases, while MGPT-MD;simulations demonstrate that the higher-energy fcc, hcp, and hex-omega;structures are only mechanically stabilized at high temperature by;large, size-dependent, anharmonic vibrational effects, with the;stability of the hex-omega phase also being found to be a sensitive;function of its c/a ratio. Both two-phase and Z-method melting;techniques have been used in MGPT-MD simulations to determine relative;phase stability and its size dependence. In the large-cell limit, the;two-phase method yields accurate equilibrium melt curves for all five;phases, with bcc producing the highest melt temperatures at all;pressures and hence being the most stable phase of those considered. The;two-phase bcc melt curve is also in good agreement with dynamic;experimental data as well as with the MGPT melt curve calculated from;bcc and liquid free energies. In contrast, we find that the Z method;produces only an upper bound to the equilibrium melt curve in the;large-cell limit. For the bcc and hex-omega structures, however, this is;a close upper bound within 5% of the two-phase results, although for the;A15, fcc, and hcp structures, the Z-melt curves are 25%-35% higher in;temperature than the two-phase results. Nonetheless, the Z method has;allowed us to study melt size effects in detail. We find these effects;to be either small or modest for the cubic bcc, A15, and fcc structures,;but to have a large impact on the hexagonal hcp and hex-omega melt;curves, which are dramatically pushed above that of bcc for simulation;cells less than 150 atoms. The melt size effects are driven by and;closely correlated with similar size effects on the mechanical stability;and the vibrational anharmonicity. We further show that for the same;simulation cell sizes and choice of c/a ratio, the MGPT-MD bcc and;hex-omega melt curves are in good agreement with the QMD results, so the;QMD prediction is confirmed in the small-cell limit. But in the;large-cell limit, the MGPT-MD hex-omega melt curve is always lowered;below that of bcc for any choice of c/a, so bcc is the most stable;phase. We conclude that for the non-bcc Ta phases studied, one requires;simulation cells of at least 250-500 atoms to be free of size effects;impacting mechanical and thermodynamic phase stability.

The energy spectrum comprises;a sequence of series of quasi-Rydberg levels relevant to the slow motion;adjacent from the low energies to the size-quantized levels associated;with the fast motion. Only the series attributed to the ground;size-quantized subband is really discrete, while others corresponding to;the excited subbands consist of quasidiscrete (Fano resonant) levels of;nonzero energetic widths, caused by the coupling with the states of the;continuous spectrum branching from the low lying subbands.

TC:0 AU: ;FN Thomson Reuters Web of Scienceâ„¢;1.0;J;Aizin, Gregory R.;Dyer, Gregory C.;Transmission line theory of collective plasma excitations in periodic;two-dimensional electron systems: Finite plasmonic crystals and Tamm;states;PHYSICAL REVIEW B;86;23;235316;10.1103/PhysRevB.86.235316;DEC 28 2012;2012;We present a comprehensive theory of the one-dimensional plasmonic;crystal formed in the grating-gated two-dimensional electron gas (2DEG);in semiconductor heterostructures. To describe collective plasma;excitations in the 2DEG, we develop a generalized transmission line;theoretical formalism consistent with the plasma hydrodynamic model. We;then apply this formalism to analyze the plasmonic spectra of 2DEG;systems with steplike periodic changes of electron density, gate;screening, or both. We show that in a periodically modulated 2DEG, a;plasmonic crystal is formed, and we derive closed-form analytical;expressions describing its energy band spectrum for both infinite and;finite size crystals. Our results demonstrate a nonmonotonic dependence;of the plasmonic band gap width on the electron density modulation. At;so-called transparency points, where the plasmon propagates through the;periodic 2DEG in a resonant manner, the plasmonic band gaps vanish. In;semi-infinite plasmonic crystals, we demonstrate the formation of;plasmonic Tamm states and analytically derive their energy dispersion;and spatial localization. Finally, we present detailed numerical;analysis of the plasmonic band structure of a finite four-period;plasmonic crystal terminated either by an ohmic contact or by an;infinite barrier on each side. We trace the evolution of the plasmonic;band spectrum, including the Tamm states, with changing electron density;modulation and analyze the boundary conditions necessary for formation;of the Tamm states. We also analyze interaction between the Tamm states;formed at the opposite edges of the short length plasmonic crystal. The;validity of our theoretical approach was confirmed in experimental;studies of plasmonic crystals in short, modulated plasmonic cavities;[Dyer et al., Phys. Rev. Lett. 109, 126803 (2012)], which demonstrated;excellent quantitative agreement between theory and experiment.;DOI:10.1103/PhysRevB.86.235316;9;0;0;0;9;1098-0121;WOS:000312833200005;;;J;Arakawa, Tomonori;Tanaka, Takahiro;Chida, Kensaku;Matsuo, Sadashige;Nishihara, Yoshitaka;Chiba, Daichi;Kobayashi, Kensuke;Ono, Teruo;Fukushima, Akio;Yuasa, Shinji;Low-frequency and shot noises in CoFeB/MgO/CoFeB magnetic tunneling;junctions;PHYSICAL REVIEW B;86;22;224423;10.1103/PhysRevB.86.224423;DEC 28 2012;2012;The low-frequency and shot noises in spin-valve CoFeB/MgO/CoFeB magnetic;tunneling junctions were studied at low temperature. The measured 1/f;noise around the magnetic hysteresis loops of the free layer indicates;that the main origin of the 1/f noise is the magnetic fluctuation, which;is discussed in terms of a fluctuation-dissipation relation. Random;telegraph noise (RTN) is observed to be symmetrically enhanced in the;hysteresis loop with regard to the two magnetic configurations. We found;that this enhancement is caused by the fluctuation between two magnetic;states in the free layer. Although the 1/f noise is almost independent;of the magnetic configuration, the RTN is enhanced in the antiparallel;configuration. These findings indicate the presence of spin-dependent;activation of RTN. Shot noise reveals the spin-dependent coherent;tunneling process via a crystalline MgO barrier.

In particular, we;probe domain walls nucleated in the free layer of the spin-valves, which;are then pinned in the devices. We have determined both the;field-current state diagrams for the domain-wall state and the thermally;activated dynamics of the nucleation and depinning processes. We show;that the nucleation process is well-described by a modified Neel-Brown;model taking into account the spin-transfer torque, whereas the;depinning process is independent of the current. This is confirmed by an;analytical calculation which shows that spin-torques have no effect on;the Arrhenius escape rate associated with thermally activated domain;wall depinning in this geometry. Furthermore, micromagnetic simulations;indicate that spin-transfer only weakly affects the domain wall motion,;but instead modifies the inner domain wall structure.

The;quasiparticle energy levels and especially the energies of the benzene;excitons (triplet, singlet, optically active and inactive) are in very;good agreement with available experimental results. It is shown that the;vicinity of the various substrates [pristine/doped graphene or (jellium);metal surface] reduces the quasiparticle highest occupied molecular;orbital-lowest unoccupied molecular orbital (HOMO-LUMO) gap by an amount;that slightly depends on the substrate type. This is consistent with the;simple image theory predictions. It is even shown that the substrate;does not change the energy of the excitons in the isolated molecule. We;prove (in terms of simple image theory) that energies of the excitons;are indeed influenced by two mechanisms which cancel each other. We;demonstrate that the benzene singlet optically active (E-1u) exciton;couples to real electronic excitations in the substrate. This causes it;substantial decay, such as Gamma approximate to 174 meV for pristine;graphene and Gamma approximate to 362 meV for metal surfaces as the;substrate.

The monoclinic;phase has the uniaxial magnetic easy axis 30 away from the [001];direction towards the [010] direction while the tetragonal phase has;uniaxial magnetic easy axis along the fourfold axis which is;perpendicular to the film surface. This study demonstrates the ability;to control the octahedral rotations in perovskite films and its;importance when designing thin films and multilayers with desired;functional property.;Chen, Jingsheng/D-9107-2011; Yang, Ping/C-5612-2008;1;0;0;0;1;1098-0121;WOS:000332161300001;;;J;Marcano, N.;Algarabel, P.

We present evidence that the high-temperature second-order;ferromagnetic transition can be coupled with the low-temperature;first-order crystallographic transformation into a single first-order;magnetic-crystallographic transformation using a magnetic field and;hydrostatic pressure as tuning parameters. The effect of pressure on the;Griffiths-like phase is reported and analyzed in the framework of the;complex competition between the interslab and intraslab magnetic;interactions.;Magen, Cesar/A-2825-2013; Morellon, Luis/K-6922-2014; Marcano Aguado, Noelia/F-9446-2010;

TC:5 AU: ;FN Thomson Reuters Web of Scienceâ„¢;1.0;J;Aizin, Gregory R.;Dyer, Gregory C.;Transmission line theory of collective plasma excitations in periodic;two-dimensional electron systems: Finite plasmonic crystals and Tamm;states;PHYSICAL REVIEW B;86;23;235316;10.1103/PhysRevB.86.235316;DEC 28 2012;2012;We present a comprehensive theory of the one-dimensional plasmonic;crystal formed in the grating-gated two-dimensional electron gas (2DEG);in semiconductor heterostructures. To describe collective plasma;excitations in the 2DEG, we develop a generalized transmission line;theoretical formalism consistent with the plasma hydrodynamic model. We;then apply this formalism to analyze the plasmonic spectra of 2DEG;systems with steplike periodic changes of electron density, gate;screening, or both. We show that in a periodically modulated 2DEG, a;plasmonic crystal is formed, and we derive closed-form analytical;expressions describing its energy band spectrum for both infinite and;finite size crystals. Our results demonstrate a nonmonotonic dependence;of the plasmonic band gap width on the electron density modulation. At;so-called transparency points, where the plasmon propagates through the;periodic 2DEG in a resonant manner, the plasmonic band gaps vanish. In;semi-infinite plasmonic crystals, we demonstrate the formation of;plasmonic Tamm states and analytically derive their energy dispersion;and spatial localization. Finally, we present detailed numerical;analysis of the plasmonic band structure of a finite four-period;plasmonic crystal terminated either by an ohmic contact or by an;infinite barrier on each side. We trace the evolution of the plasmonic;band spectrum, including the Tamm states, with changing electron density;modulation and analyze the boundary conditions necessary for formation;of the Tamm states. We also analyze interaction between the Tamm states;formed at the opposite edges of the short length plasmonic crystal. The;validity of our theoretical approach was confirmed in experimental;studies of plasmonic crystals in short, modulated plasmonic cavities;[Dyer et al., Phys. Rev.

The magnetic field dependent weak localization is found;to be well fitted by theory, which is then used to analyze the;dependence of the scattering lengths L-phi, L-i, and L-* on carrier;density. We find no significant carrier dependence for L-phi, a weak;decrease for L-i with increasing carrier density just beyond a large;standard error, and a n(-1/4) dependence for L-*.

We further show that this off-centering of the;magnetic Cr ion gives rise to a peculiar entanglement between the polar;and magnetic degrees of freedom, stabilizing, in the paramagnetic phase,;short-range magnetic clusters, clearly seen in ultralow-field;susceptibility measurements. Moreover, the Landau theory is here used to;demonstrate that a linear coupling between the magnetic and polar order;parameters is sufficient to justify the appearance of magnetic cluster;in the paramagnetic phase of this compound.

To describe collective plasma;excitations in the 2DEG, we develop a generalized transmission line;theoretical formalism consistent with the plasma hydrodynamic model. We;then apply this formalism to analyze the plasmonic spectra of 2DEG;systems with steplike periodic changes of electron density, gate;screening, or both. We show that in a periodically modulated 2DEG, a;plasmonic crystal is formed, and we derive closed-form analytical;expressions describing its energy band spectrum for both infinite and;finite size crystals. Our results demonstrate a nonmonotonic dependence;of the plasmonic band gap width on the electron density modulation. At;so-called transparency points, where the plasmon propagates through the;periodic 2DEG in a resonant manner, the plasmonic band gaps vanish. In;semi-infinite plasmonic crystals, we demonstrate the formation of;plasmonic Tamm states and analytically derive their energy dispersion;and spatial localization. Finally, we present detailed numerical;analysis of the plasmonic band structure of a finite four-period;plasmonic crystal terminated either by an ohmic contact or by an;infinite barrier on each side. We trace the evolution of the plasmonic;band spectrum, including the Tamm states, with changing electron density;modulation and analyze the boundary conditions necessary for formation;of the Tamm states. We also analyze interaction between the Tamm states;formed at the opposite edges of the short length plasmonic crystal. The;validity of our theoretical approach was confirmed in experimental;studies of plasmonic crystals in short, modulated plasmonic cavities;[Dyer et al., Phys. Rev.

The measured 1/f;noise around the magnetic hysteresis loops of the free layer indicates;that the main origin of the 1/f noise is the magnetic fluctuation, which;is discussed in terms of a fluctuation-dissipation relation. Random;telegraph noise (RTN) is observed to be symmetrically enhanced in the;hysteresis loop with regard to the two magnetic configurations. We found;that this enhancement is caused by the fluctuation between two magnetic;states in the free layer. Although the 1/f noise is almost independent;of the magnetic configuration, the RTN is enhanced in the antiparallel;configuration. These findings indicate the presence of spin-dependent;activation of RTN. Shot noise reveals the spin-dependent coherent;tunneling process via a crystalline MgO barrier.

We have determined both the;field-current state diagrams for the domain-wall state and the thermally;activated dynamics of the nucleation and depinning processes. We show;that the nucleation process is well-described by a modified Neel-Brown;model taking into account the spin-transfer torque, whereas the;depinning process is independent of the current. This is confirmed by an;analytical calculation which shows that spin-torques have no effect on;the Arrhenius escape rate associated with thermally activated domain;wall depinning in this geometry.

We fit the data to the Drude free-electron model,;with an electron relaxation time tau(D) = 14 +/- 3 fs and plasma energy;h omega(p) = 8.45 eV. We find that the variation in dielectric functions;for the different types of samples is small compared to the range of;values reported in the literature. Our values, however, are comparable;to the aggregate mean of the collection of previous measurements from;over the past six decades. This suggests that although some variation;can be attributed to surface morphology, the past measurements using;different approaches seem to have been plagued more by systematic errors;than previously assumed.

However, due to convergence problems of the Kohn-Sham;(KS) self-consistency cycle, the use of these functionals is mostly;restricted to situations where the local density is away from;half-filling. Here a numerical scheme for the self-consistent solution;of the lattice KS Hamiltonian with a local xc potential with rapid (or;quasidiscontinuous) density dependence is suggested. The problem is;formulated in terms of finite-temperature DFT where the discontinuity in;the xc potential emerges naturally in the limit of zero temperature. A;simple parametrization is suggested for the xc potential of the uniform;one-dimensional (1D) Hubbard model at finite temperature which is;obtained from the solution of the thermodynamic Bethe ansatz. The;feasibility of the numerical scheme is demonstrated by application to a;model of fermionic atoms in a harmonic trap.

With;disorder, the excitation density decays exponentially with t, with the;decay rate increasing with the disorder, to an asymptotic value;independent of the disorder. The energy and change in order parameter;also decrease as tau is increased.

In contrast to;the previously reported CaBe2Ge2-type CeNi2As2, the ThCr2Si2-type;CeNi2As2 is a highly anisotropic uniaxial antiferromagnet with the;transition temperature T-N = 4.8 K. A magnetic-field-induced spin-flop;transition was seen below T-N when the applied B is parallel to the c;axis, the magnetic easy axis, together with a huge frustration parameter;f = theta(W)/T-N. A pronounced Schottky-type anomaly in specific heat;was also found around 160 K, which could be attributed to the;crystalline electric field effect with the excitation energies being;fitted to Delta(1) = 325 K and Delta(2) = 520 K, respectively. Moreover,;the in-plane resistivity anisotropy and low-temperature x-ray;diffractions suggest that this compound is a rare example exhibiting a;possible structure distortion induced by the 4f-electron magnetic;frustration.

To describe collective plasma;excitations in the 2DEG, we develop a generalized transmission line;theoretical formalism consistent with the plasma hydrodynamic model. We;then apply this formalism to analyze the plasmonic spectra of 2DEG;systems with steplike periodic changes of electron density, gate;screening, or both. We show that in a periodically modulated 2DEG, a;plasmonic crystal is formed, and we derive closed-form analytical;expressions describing its energy band spectrum for both infinite and;finite size crystals. Our results demonstrate a nonmonotonic dependence;of the plasmonic band gap width on the electron density modulation. At;so-called transparency points, where the plasmon propagates through the;periodic 2DEG in a resonant manner, the plasmonic band gaps vanish. In;semi-infinite plasmonic crystals, we demonstrate the formation of;plasmonic Tamm states and analytically derive their energy dispersion;and spatial localization. Finally, we present detailed numerical;analysis of the plasmonic band structure of a finite four-period;plasmonic crystal terminated either by an ohmic contact or by an;infinite barrier on each side. We trace the evolution of the plasmonic;band spectrum, including the Tamm states, with changing electron density;modulation and analyze the boundary conditions necessary for formation;of the Tamm states. We also analyze interaction between the Tamm states;formed at the opposite edges of the short length plasmonic crystal. The;validity of our theoretical approach was confirmed in experimental;studies of plasmonic crystals in short, modulated plasmonic cavities;[Dyer et al., Phys. Rev.

Random;telegraph noise (RTN) is observed to be symmetrically enhanced in the;hysteresis loop with regard to the two magnetic configurations. We found;that this enhancement is caused by the fluctuation between two magnetic;states in the free layer. Although the 1/f noise is almost independent;of the magnetic configuration, the RTN is enhanced in the antiparallel;configuration.

We show that the effects of recombination barriers and of;grain refinement can be coupled to each other to produce a phenomenon of;interstitial starvation. In interstitial starvation, a significant;number of interstitials annihilate at the grain boundary, leaving behind;unrecombined vacancies, which in turn amorphize the material. The same;rate theory model with material-specific parameters was used to predict;the grain-size dependence of the critical amorphization temperature in;SiC. Parameters for the SiC model were taken from ab initio;calculations. We find that the fine-grained SiC has a lower radiation;resistance when compared to the polycrystalline SiC due to the presence;of high-energy barrier for recombination of carbon Frenkel pairs and due;to the interstitial starvation phenomenon.

The;Raman spectra show a peak centered at 380 cm(-1) starting above 6 GPa;for all samples, in agreement with previous observations. X-ray;diffraction measurements are consistent with this spectral change;indicating a structural phase transition; we find that the triplet at;the pseudocubic (220) Bragg peak merges into a doublet above 6 GPa. Our;results indicate that the morphotropic phase boundary region (x = 0.33 -;0.37) with the presence of monoclinic symmetry persists up to 7 GPa. The;pressure dependence of ferroelectric domains in PMN-0.32PT single;crystals was observed using a polarizing optical microscope. The domain;wall density decreases with pressure and the domains disappear at a;modest pressure of 3 GPa. We propose a pressure-composition phase;diagram for PMN-xPT solid solutions.

This material displays a semiconducting;character with a bulk optical gap of E-g similar or equal to 300 meV at;295 K. In addition to the two expected infrared-active vibrations;observed in the planes, there is an additional fine structure that is;attributed to either the removal of degeneracy or the activation of;Raman modes due to disorder. A strong impurity band located at similar;or equal to 200 cm(-1) is also observed. At and just above the optical;gap, several interband absorptions are found to show a strong;temperature and pressure dependence. As the temperature is lowered these;features increase in strength and harden. The application of pressure;leads to a very abrupt closing of the gap above 8 GPa, and strongly;modifies the interband absorptions in the midinfrared spectral range.;While ab initio calculations fail to predict the collapse of the gap,;they do successfully describe the size of the band gap at ambient;pressure, and the magnitude and shape of the optical conductivity.

Using real-space mean-field theory, we numerically;determine the phase as a function of the interaction strength for;different values of the gauge-field parameter. For a fixed value of the;gauge field, we observe that when the strength of the repulsive;interaction is increased, the system enters into an antiferromagnetic;phase, then undergoes a first-order phase transition to a noncollinear;magnetic phase. Depending on the gauge-field parameter, this phase;further evolves to the one predicted from the effective Heisenberg model;obtained in the limit of large interaction strength.

To describe collective plasma;excitations in the 2DEG, we develop a generalized transmission line;theoretical formalism consistent with the plasma hydrodynamic model. We;then apply this formalism to analyze the plasmonic spectra of 2DEG;systems with steplike periodic changes of electron density, gate;screening, or both. We show that in a periodically modulated 2DEG, a;plasmonic crystal is formed, and we derive closed-form analytical;expressions describing its energy band spectrum for both infinite and;finite size crystals. Our results demonstrate a nonmonotonic dependence;of the plasmonic band gap width on the electron density modulation. At;so-called transparency points, where the plasmon propagates through the;periodic 2DEG in a resonant manner, the plasmonic band gaps vanish. In;semi-infinite plasmonic crystals, we demonstrate the formation of;plasmonic Tamm states and analytically derive their energy dispersion;and spatial localization. Finally, we present detailed numerical;analysis of the plasmonic band structure of a finite four-period;plasmonic crystal terminated either by an ohmic contact or by an;infinite barrier on each side. We trace the evolution of the plasmonic;band spectrum, including the Tamm states, with changing electron density;modulation and analyze the boundary conditions necessary for formation;of the Tamm states. We also analyze interaction between the Tamm states;formed at the opposite edges of the short length plasmonic crystal. The;validity of our theoretical approach was confirmed in experimental;studies of plasmonic crystals in short, modulated plasmonic cavities;[Dyer et al., Phys. Rev.

Random;telegraph noise (RTN) is observed to be symmetrically enhanced in the;hysteresis loop with regard to the two magnetic configurations. We found;that this enhancement is caused by the fluctuation between two magnetic;states in the free layer.

Therefore inelastic;scattering processes of helical Dirac electrons become possible, as;described by a dynamical local self-energy of second order in the;exchange interaction. The self energy influences bound-state formation;and leads to significant new anomalies in the LDOS at low energies and;low temperatures, which we calculate within the T-matrix approach. We;propose that they may be used for spectroscopy of local impurity spin;states by appropriate tuning of the chemical potential and magnetic;field.

In this paper, we answer;this question for two-dimensional (2D) bosonic SPT phases with Z(N) and;U(1) symmetry. We find that while the low-energy modes of the gapless;edges are nonchiral, symmetry acts on them in a "chiral" way, i.e., acts;on the right movers and the left movers differently. This special;realization of symmetry protects the gaplessness of the otherwise;unstable edge states by prohibiting a direct scattering between the left;and right movers. Moreover, understanding of the low-energy effective;theory leads to experimental predictions about the SPT phases. In;particular, we find that all the 2D U(1) SPT phases have even integer;quantized Hall conductance.

To this end, we further develop the general,;finite-temperature real-time transport formalism by introducing field;superoperators that obey fermionic statistics. This direct second;quantization in Liouville Fock space strongly simplifies the;construction of operators and superoperators that transform irreducibly;under the Anderson-model symmetry transformations. The fermionic field;superoperators naturally arise from the univalence (fermion-parity);superselection rule of quantum mechanics for the total system of quantum;dot plus reservoirs. Expressed in these field superoperators, the causal;structure of the perturbation theory for the effective time-evolution;superoperator kernel becomes explicit. Using the constraints of the;causal structure, we construct a parametrization of the exact effective;time-evolution kernel for which we analytically find the eigenvectors;and eigenvalues in terms of a minimal set of only 30 independent;coefficients. The causal structure also implies the existence of a;fermion-parity protected eigenvector of the exact Liouvillian,;explaining a recently reported result on adiabatic driving;[Contreras-Pulido et al., Phys.

B 85, 075301 (2012)] and;generalizing it to arbitrary order in the tunnel coupling Gamma.;Furthermore, in the wide-band limit, the causal representation;exponentially reduces the number of diagrams for the time-evolution;kernel. The remaining diagrams can be identified simply by their;topology and are manifestly independent of the energy cutoff term by;term. By an exact reformulation of this series, we integrate out all;infinite-temperature effects, obtaining an expansion targeting only the;nontrivial, finite-temperature corrections, and the exactly conserved;transport current follows directly from the time-evolution kernel. From;this new series, the previously formulated RT-RG equations are obtained;naturally. We perform a complete one-plus-two-loop RG analysis at finite;voltage and magnetic field, while systematically accounting for the;dependence of all renormalized quantities on both the quantum dot and;reservoir frequencies. Using the second quantization in Liouville space;and symmetry restrictions, we obtain analytical RT-RG equations, which;can be solved numerically in an efficient way, and we extensively study;the model parameter space, excluding the Kondo regime where the;one-plus-two-loop approach is obviously invalid. The incorporated;renormalization effects result in an enhancement of the inelastic;cotunneling peak, even at a voltage similar to magnetic field similar to;tunnel coupling Gamma.

For this purpose, Ge NCs embedded in an SiO2;matrix with controllable size, density, and structure were fabricated;using magnetron sputtering. The size dependence of the Ge plasmon;energies in the size range of 5-9 nm is shown to be well depicted by the;so-called medium quantum confinement (QC) model, with an effective mass;of 0.57m(0) (contrary to expectations of a stronger quantum effect). In;the very low-loss region of the EEL spectra, an apparent blue shift of;the E-2 interband transition peak up to 2 eV and a strong reduction in;the oscillator strength were measured for the NCs in the size range of;4-6 nm. It indicates for this smaller size range a transition to a QC;regime where the band structure and the density of states are modified;dramatically. These trends are explained by a combination of low-loss;and core-loss EELS results, which show that the Ge NCs are surrounded;uniformly by nearly stoichiometric SiO2. This local chemistry is shown;to provide an infinite potential barrier and to confine electrons and;holes in the spherically shaped Ge NCs. In addition to pure QC effects;in the Ge NCs, the SiO2 matrix thus plays an important role in the;strength of the observed QC and interband transitions.

For the single-chain magnet formed by the;strongly anisotropic manganese(III) acetate meso-tetraphenylporphyrin;complexes coupled to the phenylphosphinate ligands, the experimental;metamagnetic-type magnetization curve in the c direction yields an;accurate estimate of the values of correlation energy Delta(xi)/k(B) =;7.93 K and exchange coupling J/k(B) = 1.20 K.

The formulas in the existing literature are frequently;incomplete, incorrect, or lack a derivation; in particular, Hall;viscosity is overlooked. Our approach begins from the response to a;uniform external strain field, which is an active time-dependent;coordinate transformation in d space dimensions. These transformations;form the group GL(d, R) of invertible matrices, and the infinitesimal;generators are called strain generators. These enable us to express the;Kubo formula in different ways, related by Ward identities; some of;these make contact with the adiabatic transport approach. The importance;of retaining contact terms, analogous to the diamagnetic term in the;familiar Kubo formula for conductivity, is emphasized. For;Galilean-invariant systems, we derive a relation between the stress;response tensor and the conductivity tensor that is valid at all;frequencies and in both the presence and absence of a magnetic field. In;the presence of a magnetic field and at low frequency, this yields a;relation between the Hall viscosity, the q(2) part of the Hall;conductivity, the inverse compressibility (suitably defined), and the;diverging part of the shear viscosity (if any); this relation;generalizes a result found recently by others. We show that the correct;value of the Hall viscosity at zero frequency can be obtained (at least;in the absence of low-frequency bulk and shear viscosity) by assuming;that there is an orbital spin per particle that couples to a perturbing;electromagnetic field as a magnetization per particle.

L. de Andres, F. Guinea, and M. I. Katsnelson, Phys. Rev. B;86, 144103 (2012)]. Under compression, flexural modes are responsible;for a long-wavelength rippling with a large amplitude and a marked;anharmonic behavior. This is compared with corrugations created by;thermal fluctuations and the adsorption of a light impurity (hydrogen).;Typical values for the later are in the sub-Angstrom regime, while;maximum corrugations associated to bending modes quickly increase up to;a few Angstroms under a compressive stress, due to the intrinsic;instability of flexural modes.

In the PRL paper, H-CDW was defined as a new;parameter for expressing CDW chirality for the first time. In his;Comment, he claims that H-CDW is ill defined. He also claims that the;initial phase phi of the CDW wave function is a more appropriate;parameter for expressing chiral CDW, despite our early introduction of;phi to explain the experimental data described in the PRL paper.;However, we conclude that H-CDW can distinguish the CDW chirality by its;sign. Moreover, by considering different H-CDW signs, we had succeeded;in demonstrating the difference of the spatial distributions of CDWs as;shown in Fig. 4 of the PRB paper [Phys. Rev.

We show that his argument;regarding the identification of the CDW with the opposite sign of q is;wrong, since the logic is inapplicable to a wave function with a nonzero;phi. We also discuss the applicability of H-CDW to two- or;three-dimensional CDWs in transition metal dichalcogenides.

It is shown that the Dzyaloshinskii-Moriya;interactions significantly modify the triplon dispersions around the;Gamma point and cause a shift of the spin-gap (the minimum triplon gap);position from the K to Gamma point in the first Brillouin zone. The spin;gap is also evaluated in exact diagonalization studies on a 24-site;cluster.

The islands are initially placed on the;top of the pillars, in the so-called Cassie-Baxter state. For high;pillars, the dynamics is divided into two phases. The first phase;corresponds to the deterministic and irreversible impalement of the;island. The dynamics of this phase is governed by surface diffusion.;Once the island has collapsed, a second phase is observed where the;island exhibits Brownian motion along the pillars, characterized by a;diffusion constant D-i and a kinetic coefficient K-i accounting for the;interaction of the island with the top of the pillars. The random walk;stops when the island reaches the bottom of the substrate, where it;sticks irreversibly. When the island wettability is small, the island;diffusion constant D-i is controlled by adatom diffusion, and scales as;the inverse of the number of atoms in the island. In contrast, for large;wettabilities, we observe that D-i oscillates as the island size is;increased. The minimum of the oscillations corresponds to;nucleation-limited dynamics, where D-i is independent of the island;size.

We construct a low-energy effective theory by restricting the;microscopic Hamiltonian of electrons to the space of incompressible;deformations and show that the theory of the quantum Hall edge so;obtained is a generalization of a chiral conformal field theory. In our;theory, a quasiparticle tunneling operator is found to be a;single-valued function of tunneling point coordinates, and its phase;depends on the topology determined by the positions of Ohmic contacts.;We describe strong coupling of the edge states to Ohmic contacts and the;resulting quasiparticle current through the interferometer with the help;of a master equation.

Two cases are considered. The first is the;counterflowing (Vinen) turbulence, where the vortex lines are;disordered, and the evolution of quantity L(t) obeys the Vinen equation.;The second case is the fluctuations of the VLD in a single vortex;bundle, which develops inside the domain of the concentrated;normal-fluid vorticity. The dynamics of the vortex bundle is described;by the Hall-Vinen-Bekarevich-Khalatnikov (HVBK) equations. The latter;case is of special interest, because the set of the quantum vortex;bundles is believed to mimic classical hydrodynamic turbulence. In;steady states the VLD is related to the normal velocity as L = (rho;gamma/rho(s))(2)upsilon(2)(n) for the Vinen case. In the vortex bundle;case, which appears inside the domain of a concentrated vorticity of;normal fluid, the stationary quantity L can be found from the matching;of velocities and is described by L = vertical bar del x v(n)vertical;bar/kappa. In nonstationary situations, and particularly in the;fluctuating turbulent flow, there is a retardation between the;instantaneous value of the normal velocity and the quantity L. This;retardation tends to decrease in accordance with the inner dynamics,;which has a relaxation character. In both cases, the relaxation dynamics;of the VLD is related to fluctuations of the relative velocity.

Rev. Lett. 104, 255702 (2010)]. Here we examine;possible high-T, P polymorphism in Ta with complementary DFT-based model;generalized pseudopotential theory (MGPT) multi-ion interatomic;potentials, which allow accurate treatment of much larger system sizes;(up to similar to 80000 atoms). We focus on candidate bcc, A15, fcc,;hcp, and hex-omega phases for the high-T, P phase diagram to 420 GPa,;studying the mechanical and relative thermodynamic stability of these;phases for both small and large computational cells. Our MGPT potentials;fully capture the T = 0 DFT energetics of these phases, while MGPT-MD;simulations demonstrate that the higher-energy fcc, hcp, and hex-omega;structures are only mechanically stabilized at high temperature by;large, size-dependent, anharmonic vibrational effects, with the;stability of the hex-omega phase also being found to be a sensitive;function of its c/a ratio. Both two-phase and Z-method melting;techniques have been used in MGPT-MD simulations to determine relative;phase stability and its size dependence. In the large-cell limit, the;two-phase method yields accurate equilibrium melt curves for all five;phases, with bcc producing the highest melt temperatures at all;pressures and hence being the most stable phase of those considered. The;two-phase bcc melt curve is also in good agreement with dynamic;experimental data as well as with the MGPT melt curve calculated from;bcc and liquid free energies. In contrast, we find that the Z method;produces only an upper bound to the equilibrium melt curve in the;large-cell limit. For the bcc and hex-omega structures, however, this is;a close upper bound within 5% of the two-phase results, although for the;A15, fcc, and hcp structures, the Z-melt curves are 25%-35% higher in;temperature than the two-phase results. Nonetheless, the Z method has;allowed us to study melt size effects in detail. We find these effects;to be either small or modest for the cubic bcc, A15, and fcc structures,;but to have a large impact on the hexagonal hcp and hex-omega melt;curves, which are dramatically pushed above that of bcc for simulation;cells less than 150 atoms. The melt size effects are driven by and;closely correlated with similar size effects on the mechanical stability;and the vibrational anharmonicity. We further show that for the same;simulation cell sizes and choice of c/a ratio, the MGPT-MD bcc and;hex-omega melt curves are in good agreement with the QMD results, so the;QMD prediction is confirmed in the small-cell limit. But in the;large-cell limit, the MGPT-MD hex-omega melt curve is always lowered;below that of bcc for any choice of c/a, so bcc is the most stable;phase. We conclude that for the non-bcc Ta phases studied, one requires;simulation cells of at least 250-500 atoms to be free of size effects;impacting mechanical and thermodynamic phase stability.

To describe collective plasma;excitations in the 2DEG, we develop a generalized transmission line;theoretical formalism consistent with the plasma hydrodynamic model. We;then apply this formalism to analyze the plasmonic spectra of 2DEG;systems with steplike periodic changes of electron density, gate;screening, or both. We show that in a periodically modulated 2DEG, a;plasmonic crystal is formed, and we derive closed-form analytical;expressions describing its energy band spectrum for both infinite and;finite size crystals. Our results demonstrate a nonmonotonic dependence;of the plasmonic band gap width on the electron density modulation. At;so-called transparency points, where the plasmon propagates through the;periodic 2DEG in a resonant manner, the plasmonic band gaps vanish. In;semi-infinite plasmonic crystals, we demonstrate the formation of;plasmonic Tamm states and analytically derive their energy dispersion;and spatial localization. Finally, we present detailed numerical;analysis of the plasmonic band structure of a finite four-period;plasmonic crystal terminated either by an ohmic contact or by an;infinite barrier on each side. We trace the evolution of the plasmonic;band spectrum, including the Tamm states, with changing electron density;modulation and analyze the boundary conditions necessary for formation;of the Tamm states. We also analyze interaction between the Tamm states;formed at the opposite edges of the short length plasmonic crystal. The;validity of our theoretical approach was confirmed in experimental;studies of plasmonic crystals in short, modulated plasmonic cavities;[Dyer et al., Phys. Rev. Lett. 109, 126803 (2012)], which demonstrated;excellent quantitative agreement between theory and experiment.;DOI:10.1103/PhysRevB.86.235316;9;0;0;0;9;1098-0121;WOS:000312833200005;;;J;Arakawa, Tomonori;Tanaka, Takahiro;Chida, Kensaku;Matsuo, Sadashige;Nishihara, Yoshitaka;Chiba, Daichi;Kobayashi, Kensuke;Ono, Teruo;Fukushima, Akio;Yuasa, Shinji;Low-frequency and shot noises in CoFeB/MgO/CoFeB magnetic tunneling;junctions;PHYSICAL REVIEW B;86;22;224423;10.1103/PhysRevB.86.224423;DEC 28 2012;2012;The low-frequency and shot noises in spin-valve CoFeB/MgO/CoFeB magnetic;tunneling junctions were studied at low temperature. The measured 1/f;noise around the magnetic hysteresis loops of the free layer indicates;that the main origin of the 1/f noise is the magnetic fluctuation, which;is discussed in terms of a fluctuation-dissipation relation. Random;telegraph noise (RTN) is observed to be symmetrically enhanced in the;hysteresis loop with regard to the two magnetic configurations. We found;that this enhancement is caused by the fluctuation between two magnetic;states in the free layer. Although the 1/f noise is almost independent;of the magnetic configuration, the RTN is enhanced in the antiparallel;configuration. These findings indicate the presence of spin-dependent;activation of RTN. Shot noise reveals the spin-dependent coherent;tunneling process via a crystalline MgO barrier.

In particular, we;probe domain walls nucleated in the free layer of the spin-valves, which;are then pinned in the devices. We have determined both the;field-current state diagrams for the domain-wall state and the thermally;activated dynamics of the nucleation and depinning processes. We show;that the nucleation process is well-described by a modified Neel-Brown;model taking into account the spin-transfer torque, whereas the;depinning process is independent of the current. This is confirmed by an;analytical calculation which shows that spin-torques have no effect on;the Arrhenius escape rate associated with thermally activated domain;wall depinning in this geometry. Furthermore, micromagnetic simulations;indicate that spin-transfer only weakly affects the domain wall motion,;but instead modifies the inner domain wall structure.

We find that for properly heat-treated crystals;with modest Co concentration, x = 0.028, the salient ground states;associated with iron-arsenide superconductors, i.e.,;orthorhombic/antiferromagnetic (o/afm), superconducting, and nonmagnetic;collapsed-tetragonal (cT) states can be accessed all in one sample with;reasonably small and truly hydrostatic pressure.

An objective structure (OS) is one for which a;group of atoms, called a "fundamental domain" (FD), is repeated using;specific rules of translation and rotation to build a more complex;structure.

The algorithm used;for the simulations presented here is based on the observation that;adatom and dimer motion is essentially decoupled from the elastic field.;This is exploited by decomposing the film into two parts: the weakly;bonded portion and the strongly bonded portion. The weakly bonded;portion is taken to evolve independent of the elastic field. In this way;the elastic field need only be updated infrequently.

We then show that chi(F) can be used;to locate a QCP even if nu >= 2 if we introduce boundary conditions;labeled by a twist angle N theta, where N is the system size.

The procedure is applied;to the Al-Zr system because of its importance in the development of high;strength Al-Li alloys and of bulk metallic glasses. Cohesive energies of;the studied condensed phases of the Al-Zr system (the liquid phase, the;fcc solid solution, and various orthorhombic stoichiometric compounds);are calculated using the modified embedded atom model (MEAM) in the;second-nearest-neighbor formalism (2NN). The Al-Zr MEAM-2NN potential is;parameterized in this work using ab initio and experimental data found;in the literature for the AlZr3-L1(2) structure, while its predictive;ability is confirmed for several other solid structures and for the;liquid phase. The thermodynamic integration (TI) method is implemented;in a general MC algorithm in order to evaluate the absolute Gibbs energy;of the liquid and the fcc solutions. The entropy of mixing calculated;from the TI method, combined to the enthalpy of mixing and the heat;capacity data generated from MD/MC simulations performed in the;isobaric-isothermal/canonical (NPT/NVT) ensembles are used to;parameterize the Gibbs energy function of all the condensed phases in;the Al-rich side of the Al-Zr system in a CALculation of PHAse Diagrams;(CALPHAD) approach. The modified quasichemical model in the pair;approximation (MQMPA) and the cluster variation method (CVM) in the;tetrahedron approximation are used to define the Gibbs energy of the;liquid and the fcc solid solution respectively for their entire range of;composition. Thermodynamic and structural data generated from our MD/MC;simulations are used as input data to parameterize these thermodynamic;models. A detailed analysis of the validity and transferability of the;Al-Zr MEAM-2NN potential is presented throughout our work by comparing;the predicted properties obtained from this formalism with available ab;initio and experimental data for both liquid and solid phases.

Further, the;Joule heating dissipation contribution and the noise-equivalent;dissipation energy were reduced by setting a smaller amplitude. Usage of;a high resonance frequency and a smaller amplitude enables us to perform;highly sensitive measurements of the atomic-scale adhesion and the;tip-instability-related energy dissipation. Tip changes, caused by;tip-sample interactions and thermal energy, resulted in three different;dissipation energy levels (Delta E-ts approximate to 25 meV/cycle). This;infrequent change of the tip apex condition often prevents a stable;imaging with small amplitude. Our systematic measurement shows that the;atomic adhesion is caused mainly in the tip itself, and a sharper and;softer tip induced a larger energy dissipation.

Currently,;crystalline defects such as dislocations limit the performance of these;materials. Atomistic simulations are a powerful method for exploring;crystalline defects at a resolution unattainable by experimental;techniques. To enable accurate atomistic simulations of defects in the;Cd-Zn-Te systems, we develop a full Cd-Zn-Te ternary bond-order;potential. This Cd-Zn-Te potential has numerous unique advantages over;other potential formulations: (1) It is analytically derived from;quantum mechanical theories and is therefore more likely to be;transferable to environments that are not explicitly tested. (2) A;variety of elemental and compound configurations (with coordination;varying from 1 to 12) including small clusters, bulk lattices, defects,;and surfaces are explicitly considered during parameterization. As a;result, the potential captures structural and property trends close to;those seen in experiments and quantum mechanical calculations and;provides a good description of melting temperature, defect;characteristics, and surface reconstructions. (3) Most importantly, this;potential is validated to correctly predict the crystalline growth of;the ground-state structures for Cd, Zn, Te elements as well as CdTe,;ZnTe, and Cd1-xZnxTe compounds during highly challenging molecular;dynamics vapor deposition simulations.

We find that the half-metallicity of CrO2;remains intact for the ground state of all of the calculated;substitutions. We also observe two periodic trends as a function of the;number of valence electrons: if the substituted atom has six or fewer;valence electrons, the number of down spin electrons associated with the;impurity ion is zero, resulting in ferromagnetic alignment of the;impurity magnetic moment with the magnetization of the CrO2 host. For;substituent atoms with eight to ten valence electrons (with the;exception of Ni), the number of down-spin electrons contributed by the;impurity ion remains fixed at three as the number contributed to the;majority increases from one to three resulting in antiferromagnetic;alignment between impurity moment and host magnetization. In impurities;with seven valence electrons, the zero down-spin and threse down-spin;configurations are very close in energy. At 11 valence electrons, the;energy is minimized when the substituent ion contributes five down-spin;electrons. The moments on the 4d impurities, particularly Nb and Mo,;tend to be delocalized compared with those of the 3ds.

A transfer matrix;formalism for cylindrical multilayered structures is used in association;with cavity phase matching considerations to design structures that;support Tamm plasmon polaritons at specified frequencies, and to explore;the field distributions and the dispersion relations of the excitations.;The cylindrical TPPs can exist in both the TE and TM polarizations for;the special cases of modes with either azimuthal isotropy or zero axial;propagation constant and also as hybrid cylindrical modes when neither;of those conditions applies. In the cases considered the TPPs have low;effective masses and low group velocities. Also, when there is both;metallic core and cladding, near degenerate modes localized at each;metallic interface can couple to produce symmetric and antisymmetric;combinations whose frequency difference is in the terahertz regime.

The formulas in the existing literature are frequently;incomplete, incorrect, or lack a derivation; in particular, Hall;viscosity is overlooked. Our approach begins from the response to a;uniform external strain field, which is an active time-dependent;coordinate transformation in d space dimensions. These transformations;form the group GL(d, R) of invertible matrices, and the infinitesimal;generators are called strain generators. These enable us to express the;Kubo formula in different ways, related by Ward identities; some of;these make contact with the adiabatic transport approach.

For;Galilean-invariant systems, we derive a relation between the stress;response tensor and the conductivity tensor that is valid at all;frequencies and in both the presence and absence of a magnetic field.

Two cases are considered. The first is the;counterflowing (Vinen) turbulence, where the vortex lines are;disordered, and the evolution of quantity L(t) obeys the Vinen equation.;The second case is the fluctuations of the VLD in a single vortex;bundle, which develops inside the domain of the concentrated;normal-fluid vorticity. The dynamics of the vortex bundle is described;by the Hall-Vinen-Bekarevich-Khalatnikov (HVBK) equations. The latter;case is of special interest, because the set of the quantum vortex;bundles is believed to mimic classical hydrodynamic turbulence. In;steady states the VLD is related to the normal velocity as L = (rho;gamma/rho(s))(2)upsilon(2)(n) for the Vinen case. In the vortex bundle;case, which appears inside the domain of a concentrated vorticity of;normal fluid, the stationary quantity L can be found from the matching;of velocities and is described by L = vertical bar del x v(n)vertical;bar/kappa. In nonstationary situations, and particularly in the;fluctuating turbulent flow, there is a retardation between the;instantaneous value of the normal velocity and the quantity L. This;retardation tends to decrease in accordance with the inner dynamics,;which has a relaxation character. In both cases, the relaxation dynamics;of the VLD is related to fluctuations of the relative velocity. However,;for the Vinen case the rate of temporal change for L(t) is directly;dependent upon delta v(ns), whereas for HVBK dynamics it depends on del;x delta v(ns). Therefore, for the disordered case the spectrum coincides with the spectrum omega(-5/3). In the;case of the bundle arrangement, the spectrum of the VLD varies (at;different temperatures) from omega(1/3) to omega(-5/3) dependencies.;This conclusion may serve as a basis for the experimental determination;of what kind of turbulence is implemented in different types of;generation.;0;0;0;0;0;1098-0121;WOS:000312064300005;;;J;Peelaers, H.;Van de Walle, C.

While the main;contribution sigma(0)(omega) to the conductivity comes from local;dipole-type excitations on close pairs of sites, coherent processes on;three or more sites lead to an interference correction sigma(1)(omega),;which depends on the statistics of the charge carriers and can be;suppressed by a magnetic field. For bosons the correction is always;positive, while for fermions it can be positive or negative depending on;whether the conduction is dominated by effective single-particle or;single-hole processes. We calculate the conductivity explicitly assuming;a constant density of states of single-site excitations. Independently;of the statistics, sigma(0)(omega) = const. For bosons, sigma(1)(omega);proportional to log(C/omega). For fermions, sigma(1)(omega) proportional;to log[max(A,omega)/omega] - log[max(B,omega)/omega], where the first;and the second term are, respectively, the particle and hole;contributions, A and B being the particle and hole energy cutoffs.

From DFT;calculations for limiting (periodic) models, we can sample the potential;landscape of the cobalt and oxygen atoms in the Moire structure across;the Ir(100) unit cell. We find that despite the non-commensurability of;the film, the binding to the substrate is site specific with strong;attraction and repulsion points for both cobalt and oxygen atoms,;leading to severe local distortions in the film. The lateral modulation;of the structural elements within the oxide film can be understood as a;combination of the lateral variation in the Co-Ir binding potential and;additional O-Ir binding.

Here we examine;possible high-T, P polymorphism in Ta with complementary DFT-based model;generalized pseudopotential theory (MGPT) multi-ion interatomic;potentials, which allow accurate treatment of much larger system sizes;(up to similar to 80000 atoms). We focus on candidate bcc, A15, fcc,;hcp, and hex-omega phases for the high-T, P phase diagram to 420 GPa,;studying the mechanical and relative thermodynamic stability of these;phases for both small and large computational cells. Our MGPT potentials;fully capture the T = 0 DFT energetics of these phases, while MGPT-MD;simulations demonstrate that the higher-energy fcc, hcp, and hex-omega;structures are only mechanically stabilized at high temperature by;large, size-dependent, anharmonic vibrational effects, with the;stability of the hex-omega phase also being found to be a sensitive;function of its c/a ratio. Both two-phase and Z-method melting;techniques have been used in MGPT-MD simulations to determine relative;phase stability and its size dependence. In the large-cell limit, the;two-phase method yields accurate equilibrium melt curves for all five;phases, with bcc producing the highest melt temperatures at all;pressures and hence being the most stable phase of those considered. The;two-phase bcc melt curve is also in good agreement with dynamic;experimental data as well as with the MGPT melt curve calculated from;bcc and liquid free energies. In contrast, we find that the Z method;produces only an upper bound to the equilibrium melt curve in the;large-cell limit. For the bcc and hex-omega structures, however, this is;a close upper bound within 5% of the two-phase results, although for the;A15, fcc, and hcp structures, the Z-melt curves are 25%-35% higher in;temperature than the two-phase results. Nonetheless, the Z method has;allowed us to study melt size effects in detail. We find these effects;to be either small or modest for the cubic bcc, A15, and fcc structures,;but to have a large impact on the hexagonal hcp and hex-omega melt;curves, which are dramatically pushed above that of bcc for simulation;cells less than 150 atoms. The melt size effects are driven by and;closely correlated with similar size effects on the mechanical stability;and the vibrational anharmonicity. We further show that for the same;simulation cell sizes and choice of c/a ratio, the MGPT-MD bcc and;hex-omega melt curves are in good agreement with the QMD results, so the;QMD prediction is confirmed in the small-cell limit. But in the;large-cell limit, the MGPT-MD hex-omega melt curve is always lowered;below that of bcc for any choice of c/a, so bcc is the most stable;phase. We conclude that for the non-bcc Ta phases studied, one requires;simulation cells of at least 250-500 atoms to be free of size effects;impacting mechanical and thermodynamic phase stability.

The kinetic inductance is calculated;for the response to a small alternating current when the film is;carrying a dc bias current. In the slow-experiment/fast-relaxation;limit, in which the superconducting order parameter quasistatically;follows the time-dependent current, the kinetic inductance diverges as;the bias current approaches the depairing value. However, in the;fast-experiment/slow-relaxiation limit, in which the the superconducting;order parameter remains fixed at a value corresponding to the dc bias;current, the kinetic inductance rises to a finite value at the depairing;current. We then use time-dependent GL theory to calculate the kinetic;impedance of the superfluid, which includes not only the kinetic;reactance, but also the kinetic resistance of the superfluid arising;from dissipation due to order-parameter relaxation. The kinetic;resistance is largest for angular frequencies omega obeying omega tau(s);> 1, where tau(s) is the order-parameter relaxation time, and for bias;currents close to the depairing current. We also include the normal;fluid's contribution to dissipation in deriving an expression for the;total kinetic impedance. The Appendices contain many details about the;temperature-dependent behavior of superconductors carrying current up to;the depairing value.;3;0;0;0;3;1098-0121;WOS:000311714600005;;;J;Cohn, J.

To describe collective plasma;excitations in the 2DEG, we develop a generalized transmission line;theoretical formalism consistent with the plasma hydrodynamic model. We;then apply this formalism to analyze the plasmonic spectra of 2DEG;systems with steplike periodic changes of electron density, gate;screening, or both. We show that in a periodically modulated 2DEG, a;plasmonic crystal is formed, and we derive closed-form analytical;expressions describing its energy band spectrum for both infinite and;finite size crystals. Our results demonstrate a nonmonotonic dependence;of the plasmonic band gap width on the electron density modulation. At;so-called transparency points, where the plasmon propagates through the;periodic 2DEG in a resonant manner, the plasmonic band gaps vanish. In;semi-infinite plasmonic crystals, we demonstrate the formation of;plasmonic Tamm states and analytically derive their energy dispersion;and spatial localization. Finally, we present detailed numerical;analysis of the plasmonic band structure of a finite four-period;plasmonic crystal terminated either by an ohmic contact or by an;infinite barrier on each side. We trace the evolution of the plasmonic;band spectrum, including the Tamm states, with changing electron density;modulation and analyze the boundary conditions necessary for formation;of the Tamm states. We also analyze interaction between the Tamm states;formed at the opposite edges of the short length plasmonic crystal. The;validity of our theoretical approach was confirmed in experimental;studies of plasmonic crystals in short, modulated plasmonic cavities;[Dyer et al., Phys. Rev.

Random;telegraph noise (RTN) is observed to be symmetrically enhanced in the;hysteresis loop with regard to the two magnetic configurations. We found;that this enhancement is caused by the fluctuation between two magnetic;states in the free layer.

The problem is;formulated in terms of finite-temperature DFT where the discontinuity in;the xc potential emerges naturally in the limit of zero temperature. A;simple parametrization is suggested for the xc potential of the uniform;one-dimensional (1D) Hubbard model at finite temperature which is;obtained from the solution of the thermodynamic Bethe ansatz. The;feasibility of the numerical scheme is demonstrated by application to a;model of fermionic atoms in a harmonic trap. The corresponding density;profile exhibits a plateau of integer occupation at low temperatures;which melts away for higher temperatures.

Regrettably, themechanism(s);responsible for the superconductivity has yet to be unequivocally;identified. High pressure is an important variable since its application;moderates the pairing interaction. Thus far, the LnFePO (Ln = La, Pr,;Nd, Sm, Gd) family of superconductors has received relatively little;attention. Early high-pressure studies on LaFePO found that T-c;initially increased with pressure before passing through a maximum at;higher pressures. The present studies on both polycrystalline and;single-crystalline LaFePO, PrFePO, and NdFePO utilize the most;hydrostatic pressure medium available, i.e., dense He.

It is suggested that disorder creates isolated pseudospins which;become centers of inelastic scattering of electrons. It is suggested;that this scattering is responsible for the logarithmic upturn in the;resistivity rho(T) similar to - ln T observed at low doping.

This is in sharp contrast to the reported frequency branch alpha;in the quantum oscillation experiments showing a three-fold splitting;that disappears by a small field tilt, which can be explained by the;magnetic breakdown between the large hole sphere and small electron;pockets. Our analysis of the cyclotron resonance profiles reveals that;the heavier branch of the split line has a larger scattering rate,;providing evidence for the existence of hot-spot regions along the [110];direction.

TC:0 AU: ;FN Thomson Reuters Web of Scienceâ„¢;1.0;J;Aizin, Gregory R.;Dyer, Gregory C.;Transmission line theory of collective plasma excitations in periodic;two-dimensional electron systems: Finite plasmonic crystals and Tamm;states;PHYSICAL REVIEW B;86;23;235316;10.1103/PhysRevB.86.235316;DEC 28 2012;2012;We present a comprehensive theory of the one-dimensional plasmonic;crystal formed in the grating-gated two-dimensional electron gas (2DEG);in semiconductor heterostructures. To describe collective plasma;excitations in the 2DEG, we develop a generalized transmission line;theoretical formalism consistent with the plasma hydrodynamic model. We;then apply this formalism to analyze the plasmonic spectra of 2DEG;systems with steplike periodic changes of electron density, gate;screening, or both. We show that in a periodically modulated 2DEG, a;plasmonic crystal is formed, and we derive closed-form analytical;expressions describing its energy band spectrum for both infinite and;finite size crystals. Our results demonstrate a nonmonotonic dependence;of the plasmonic band gap width on the electron density modulation. At;so-called transparency points, where the plasmon propagates through the;periodic 2DEG in a resonant manner, the plasmonic band gaps vanish. In;semi-infinite plasmonic crystals, we demonstrate the formation of;plasmonic Tamm states and analytically derive their energy dispersion;and spatial localization. Finally, we present detailed numerical;analysis of the plasmonic band structure of a finite four-period;plasmonic crystal terminated either by an ohmic contact or by an;infinite barrier on each side. We trace the evolution of the plasmonic;band spectrum, including the Tamm states, with changing electron density;modulation and analyze the boundary conditions necessary for formation;of the Tamm states. We also analyze interaction between the Tamm states;formed at the opposite edges of the short length plasmonic crystal. The;validity of our theoretical approach was confirmed in experimental;studies of plasmonic crystals in short, modulated plasmonic cavities;[Dyer et al., Phys. Rev. Lett. 109, 126803 (2012)], which demonstrated;excellent quantitative agreement between theory and experiment.;DOI:10.1103/PhysRevB.86.235316;9;0;0;0;9;1098-0121;WOS:000312833200005;;;J;Arakawa, Tomonori;Tanaka, Takahiro;Chida, Kensaku;Matsuo, Sadashige;Nishihara, Yoshitaka;Chiba, Daichi;Kobayashi, Kensuke;Ono, Teruo;Fukushima, Akio;Yuasa, Shinji;Low-frequency and shot noises in CoFeB/MgO/CoFeB magnetic tunneling;junctions;PHYSICAL REVIEW B;86;22;224423;10.1103/PhysRevB.86.224423;DEC 28 2012;2012;The low-frequency and shot noises in spin-valve CoFeB/MgO/CoFeB magnetic;tunneling junctions were studied at low temperature. The measured 1/f;noise around the magnetic hysteresis loops of the free layer indicates;that the main origin of the 1/f noise is the magnetic fluctuation, which;is discussed in terms of a fluctuation-dissipation relation. Random;telegraph noise (RTN) is observed to be symmetrically enhanced in the;hysteresis loop with regard to the two magnetic configurations. We found;that this enhancement is caused by the fluctuation between two magnetic;states in the free layer. Although the 1/f noise is almost independent;of the magnetic configuration, the RTN is enhanced in the antiparallel;configuration. These findings indicate the presence of spin-dependent;activation of RTN. Shot noise reveals the spin-dependent coherent;tunneling process via a crystalline MgO barrier.

In particular, we;probe domain walls nucleated in the free layer of the spin-valves, which;are then pinned in the devices. We have determined both the;field-current state diagrams for the domain-wall state and the thermally;activated dynamics of the nucleation and depinning processes. We show;that the nucleation process is well-described by a modified Neel-Brown;model taking into account the spin-transfer torque, whereas the;depinning process is independent of the current. This is confirmed by an;analytical calculation which shows that spin-torques have no effect on;the Arrhenius escape rate associated with thermally activated domain;wall depinning in this geometry. Furthermore, micromagnetic simulations;indicate that spin-transfer only weakly affects the domain wall motion,;but instead modifies the inner domain wall structure.

The thermodynamic integration (TI) method is implemented;in a general MC algorithm in order to evaluate the absolute Gibbs energy;of the liquid and the fcc solutions. The entropy of mixing calculated;from the TI method, combined to the enthalpy of mixing and the heat;capacity data generated from MD/MC simulations performed in the;isobaric-isothermal/canonical (NPT/NVT) ensembles are used to;parameterize the Gibbs energy function of all the condensed phases in;the Al-rich side of the Al-Zr system in a CALculation of PHAse Diagrams;(CALPHAD) approach.

Using this coupling, we demonstrate an easy-to-form, stable,;nondestructive, and electrically rewritable switch on magnetic domain;wall propagation.

Currently,;crystalline defects such as dislocations limit the performance of these;materials. Atomistic simulations are a powerful method for exploring;crystalline defects at a resolution unattainable by experimental;techniques. To enable accurate atomistic simulations of defects in the;Cd-Zn-Te systems, we develop a full Cd-Zn-Te ternary bond-order;potential. This Cd-Zn-Te potential has numerous unique advantages over;other potential formulations: (1) It is analytically derived from;quantum mechanical theories and is therefore more likely to be;transferable to environments that are not explicitly tested. (2) A;variety of elemental and compound configurations (with coordination;varying from 1 to 12) including small clusters, bulk lattices, defects,;and surfaces are explicitly considered during parameterization. As a;result, the potential captures structural and property trends close to;those seen in experiments and quantum mechanical calculations and;provides a good description of melting temperature, defect;characteristics, and surface reconstructions. (3) Most importantly, this;potential is validated to correctly predict the crystalline growth of;the ground-state structures for Cd, Zn, Te elements as well as CdTe,;ZnTe, and Cd1-xZnxTe compounds during highly challenging molecular;dynamics vapor deposition simulations.

For;substituent atoms with eight to ten valence electrons (with the;exception of Ni), the number of down-spin electrons contributed by the;impurity ion remains fixed at three as the number contributed to the;majority increases from one to three resulting in antiferromagnetic;alignment between impurity moment and host magnetization.

At 11 valence electrons, the;energy is minimized when the substituent ion contributes five down-spin;electrons.

To describe collective plasma;excitations in the 2DEG, we develop a generalized transmission line;theoretical formalism consistent with the plasma hydrodynamic model. We;then apply this formalism to analyze the plasmonic spectra of 2DEG;systems with steplike periodic changes of electron density, gate;screening, or both. We show that in a periodically modulated 2DEG, a;plasmonic crystal is formed, and we derive closed-form analytical;expressions describing its energy band spectrum for both infinite and;finite size crystals. Our results demonstrate a nonmonotonic dependence;of the plasmonic band gap width on the electron density modulation. At;so-called transparency points, where the plasmon propagates through the;periodic 2DEG in a resonant manner, the plasmonic band gaps vanish. In;semi-infinite plasmonic crystals, we demonstrate the formation of;plasmonic Tamm states and analytically derive their energy dispersion;and spatial localization. Finally, we present detailed numerical;analysis of the plasmonic band structure of a finite four-period;plasmonic crystal terminated either by an ohmic contact or by an;infinite barrier on each side. We trace the evolution of the plasmonic;band spectrum, including the Tamm states, with changing electron density;modulation and analyze the boundary conditions necessary for formation;of the Tamm states. We also analyze interaction between the Tamm states;formed at the opposite edges of the short length plasmonic crystal. The;validity of our theoretical approach was confirmed in experimental;studies of plasmonic crystals in short, modulated plasmonic cavities;[Dyer et al., Phys. Rev. Lett. 109, 126803 (2012)], which demonstrated;excellent quantitative agreement between theory and experiment.;DOI:10.1103/PhysRevB.86.235316;9;0;0;0;9;1098-0121;WOS:000312833200005;;;J;Arakawa, Tomonori;Tanaka, Takahiro;Chida, Kensaku;Matsuo, Sadashige;Nishihara, Yoshitaka;Chiba, Daichi;Kobayashi, Kensuke;Ono, Teruo;Fukushima, Akio;Yuasa, Shinji;Low-frequency and shot noises in CoFeB/MgO/CoFeB magnetic tunneling;junctions;PHYSICAL REVIEW B;86;22;224423;10.1103/PhysRevB.86.224423;DEC 28 2012;2012;The low-frequency and shot noises in spin-valve CoFeB/MgO/CoFeB magnetic;tunneling junctions were studied at low temperature. The measured 1/f;noise around the magnetic hysteresis loops of the free layer indicates;that the main origin of the 1/f noise is the magnetic fluctuation, which;is discussed in terms of a fluctuation-dissipation relation. Random;telegraph noise (RTN) is observed to be symmetrically enhanced in the;hysteresis loop with regard to the two magnetic configurations. We found;that this enhancement is caused by the fluctuation between two magnetic;states in the free layer. Although the 1/f noise is almost independent;of the magnetic configuration, the RTN is enhanced in the antiparallel;configuration. These findings indicate the presence of spin-dependent;activation of RTN. Shot noise reveals the spin-dependent coherent;tunneling process via a crystalline MgO barrier.

We have determined both the;field-current state diagrams for the domain-wall state and the thermally;activated dynamics of the nucleation and depinning processes. We show;that the nucleation process is well-described by a modified Neel-Brown;model taking into account the spin-transfer torque, whereas the;depinning process is independent of the current. This is confirmed by an;analytical calculation which shows that spin-torques have no effect on;the Arrhenius escape rate associated with thermally activated domain;wall depinning in this geometry.

This is possible owing;to the extreme sensitivity of the o/afm (for T <= T-s,T-N) and;superconducting (T <= T-c) states against variation of pressure,;disclosing pressure coefficients of dT(s,N)/dP = -(1100 +/- 50) K/GPa;and dT(c)/dP = -(60 +/- 3) K/GPa, respectively. Systematic;investigations of the various phase transitions and ground states via;pressure tuning revealed no coexistence of bulk superconductivity (sc);with the o/afm state which we link to the strongly first-order character;of the corresponding structural/magnetic transition in this compound.;Our results, together with literature results, indicate that preserving;fluctuations associated with the o/afm transition to low enough;temperatures is vital for sc to form.

An objective structure (OS) is one for which a;group of atoms, called a "fundamental domain" (FD), is repeated using;specific rules of translation and rotation to build a more complex;structure. An objective Cauchy-Born rule defines the kinematics of the;OS atoms in terms of a set of symmetry parameters and the positions of;the FD atoms. The computational advantage lies in the capability of;representing a large system of atoms through a small set of symmetry;parameters and FD atom positions.

OQC simulations are performed for uniform and;nonuniform bending for two different orientations (nanobeam axis;oriented along [111] and [100]) and compared with elastica results. In;the uniform bending case, the [111]-oriented single-crystal nanobeam;experiences elongation, while the [100]-oriented nanobeam experiences;contraction in total length.

By tuning;the interpulse separation, remarkably distinct responses have been;observed in the two samples. To understand the results obtained a;phenomenological model taking the delayed formation of coherent LOPC;modes into account is proposed. The model suggests that the lifetime of;coherent LOPC modes plays a key role and the interference of the;coherent LO phonons excited successively by two pump pulses strongly;affects the manipulation of coherent LOPC modes.;DOI:10.1103/PhysRevB.86.235145;Oleg, Misochko/E-6136-2013; Nakamura, Kazutaka/F-4095-2014;0;0;0;0;0;1098-0121;WOS:000312833200001;;;J;Imura, Ken-Ichiro;Okamoto, Mayuko;Yoshimura, Yukinori;Takane, Yositake;Ohtsuki, Tomi;Finite-size energy gap in weak and strong topological insulators;PHYSICAL REVIEW B;86;24;245436;10.1103/PhysRevB.86.245436;DEC 28 2012;2012;The nontrivialness of a topological insulator (TI) is characterized;either by a bulk topological invariant or by the existence of a;protected metallic surface state. Yet, in realistic samples of finite;size, this nontrivialness does not necessarily guarantee the gaplessness;of the surface state. Depending on the geometry and on the topological;indices, a finite-size energy gap of different nature can appear, and,;correspondingly, exhibit various scaling behaviors of the gap. The;spin-to-surface locking provides one such gap-opening mechanism,;resulting in a power-law scaling of the energy gap. Weak and strong TIs;show different degrees of sensitivity to the geometry of the sample. As;a noteworthy example, a strong TI nanowire of a rectangular-prism shape;is shown to be more gapped than that of a weak TI of precisely the same;geometry.

An emphasis has been pointed towards the magnetic;structure and the interaction between the Co ions leading to magnetic;frustrations in this compound. Neutron diffraction experiments were;carried out both in the ground state (zero magnetic field) and under;applied external field of 2.5 and 5 T corresponding to the ferrimagnetic;and ferromagnetic states, respectively. The antiferromagnetic ground;state below 14 K corresponds to k = (1,0, 1/2) magnetic propagation;vector in C1 space group. The magnetic structure can be described by;ferromagnetic interactions along the chains (b axis) and;antiferromagnetic coupling between the chains (along a and c axes). The;ferrimagnetic structure implies a ninefold unit cell (3a, b, 3c) in;which ferromagnetic chains follow an "up-up-down" sequence along the a;and c axes. In the ferromagnetic state, the spin orientations remain;unchanged while every chain lies ferromagnetically ordered. In all;cases, the magnetic moments lie in the ac plane, along the CoO6;octahedra axis, at an angle of 9.3 degrees with respect to the c axis.;The magnetic structure of alpha-CoV2O6 resolved for all the ordered;states is successfully related to a theoretical model. Ab initio;calculations allowed us to (i) confirm the ground-state magnetic;structure, (ii) calculate the interactions between the Co ions, (iii);explain the frustration leading to the stepped variation of the;magnetization curves, (iv) calculate the orbital magnetic moment (1.5;mu(B)) on Co atoms, and (v) confirm the direction of the magnetic;moments near the c direction.

To describe collective plasma;excitations in the 2DEG, we develop a generalized transmission line;theoretical formalism consistent with the plasma hydrodynamic model. We;then apply this formalism to analyze the plasmonic spectra of 2DEG;systems with steplike periodic changes of electron density, gate;screening, or both. We show that in a periodically modulated 2DEG, a;plasmonic crystal is formed, and we derive closed-form analytical;expressions describing its energy band spectrum for both infinite and;finite size crystals. Our results demonstrate a nonmonotonic dependence;of the plasmonic band gap width on the electron density modulation. At;so-called transparency points, where the plasmon propagates through the;periodic 2DEG in a resonant manner, the plasmonic band gaps vanish. In;semi-infinite plasmonic crystals, we demonstrate the formation of;plasmonic Tamm states and analytically derive their energy dispersion;and spatial localization. Finally, we present detailed numerical;analysis of the plasmonic band structure of a finite four-period;plasmonic crystal terminated either by an ohmic contact or by an;infinite barrier on each side. We trace the evolution of the plasmonic;band spectrum, including the Tamm states, with changing electron density;modulation and analyze the boundary conditions necessary for formation;of the Tamm states. We also analyze interaction between the Tamm states;formed at the opposite edges of the short length plasmonic crystal. The;validity of our theoretical approach was confirmed in experimental;studies of plasmonic crystals in short, modulated plasmonic cavities;[Dyer et al., Phys. Rev.

Random;telegraph noise (RTN) is observed to be symmetrically enhanced in the;hysteresis loop with regard to the two magnetic configurations. We found;that this enhancement is caused by the fluctuation between two magnetic;states in the free layer.

We show that the effects of recombination barriers and of;grain refinement can be coupled to each other to produce a phenomenon of;interstitial starvation. In interstitial starvation, a significant;number of interstitials annihilate at the grain boundary, leaving behind;unrecombined vacancies, which in turn amorphize the material. The same;rate theory model with material-specific parameters was used to predict;the grain-size dependence of the critical amorphization temperature in;SiC. Parameters for the SiC model were taken from ab initio;calculations. We find that the fine-grained SiC has a lower radiation;resistance when compared to the polycrystalline SiC due to the presence;of high-energy barrier for recombination of carbon Frenkel pairs and due;to the interstitial starvation phenomenon.

Regrettably, themechanism(s);responsible for the superconductivity has yet to be unequivocally;identified. High pressure is an important variable since its application;moderates the pairing interaction. Thus far, the LnFePO (Ln = La, Pr,;Nd, Sm, Gd) family of superconductors has received relatively little;attention. Early high-pressure studies on LaFePO found that T-c;initially increased with pressure before passing through a maximum at;higher pressures. The present studies on both polycrystalline and;single-crystalline LaFePO, PrFePO, and NdFePO utilize the most;hydrostatic pressure medium available, i.e., dense He.

Therefore inelastic;scattering processes of helical Dirac electrons become possible, as;described by a dynamical local self-energy of second order in the;exchange interaction. The self energy influences bound-state formation;and leads to significant new anomalies in the LDOS at low energies and;low temperatures, which we calculate within the T-matrix approach. We;propose that they may be used for spectroscopy of local impurity spin;states by appropriate tuning of the chemical potential and magnetic;field.

In this paper, we answer;this question for two-dimensional (2D) bosonic SPT phases with Z(N) and;U(1) symmetry. We find that while the low-energy modes of the gapless;edges are nonchiral, symmetry acts on them in a "chiral" way, i.e., acts;on the right movers and the left movers differently. This special;realization of symmetry protects the gaplessness of the otherwise;unstable edge states by prohibiting a direct scattering between the left;and right movers. Moreover, understanding of the low-energy effective;theory leads to experimental predictions about the SPT phases. In;particular, we find that all the 2D U(1) SPT phases have even integer;quantized Hall conductance.

To this end, we further develop the general,;finite-temperature real-time transport formalism by introducing field;superoperators that obey fermionic statistics. This direct second;quantization in Liouville Fock space strongly simplifies the;construction of operators and superoperators that transform irreducibly;under the Anderson-model symmetry transformations. The fermionic field;superoperators naturally arise from the univalence (fermion-parity);superselection rule of quantum mechanics for the total system of quantum;dot plus reservoirs. Expressed in these field superoperators, the causal;structure of the perturbation theory for the effective time-evolution;superoperator kernel becomes explicit. Using the constraints of the;causal structure, we construct a parametrization of the exact effective;time-evolution kernel for which we analytically find the eigenvectors;and eigenvalues in terms of a minimal set of only 30 independent;coefficients. The causal structure also implies the existence of a;fermion-parity protected eigenvector of the exact Liouvillian,;explaining a recently reported result on adiabatic driving;[Contreras-Pulido et al., Phys.

B 85, 075301 (2012)] and;generalizing it to arbitrary order in the tunnel coupling Gamma.;Furthermore, in the wide-band limit, the causal representation;exponentially reduces the number of diagrams for the time-evolution;kernel. The remaining diagrams can be identified simply by their;topology and are manifestly independent of the energy cutoff term by;term. By an exact reformulation of this series, we integrate out all;infinite-temperature effects, obtaining an expansion targeting only the;nontrivial, finite-temperature corrections, and the exactly conserved;transport current follows directly from the time-evolution kernel. From;this new series, the previously formulated RT-RG equations are obtained;naturally. We perform a complete one-plus-two-loop RG analysis at finite;voltage and magnetic field, while systematically accounting for the;dependence of all renormalized quantities on both the quantum dot and;reservoir frequencies. Using the second quantization in Liouville space;and symmetry restrictions, we obtain analytical RT-RG equations, which;can be solved numerically in an efficient way, and we extensively study;the model parameter space, excluding the Kondo regime where the;one-plus-two-loop approach is obviously invalid. The incorporated;renormalization effects result in an enhancement of the inelastic;cotunneling peak, even at a voltage similar to magnetic field similar to;tunnel coupling Gamma.

For this purpose, Ge NCs embedded in an SiO2;matrix with controllable size, density, and structure were fabricated;using magnetron sputtering. The size dependence of the Ge plasmon;energies in the size range of 5-9 nm is shown to be well depicted by the;so-called medium quantum confinement (QC) model, with an effective mass;of 0.57m(0) (contrary to expectations of a stronger quantum effect). In;the very low-loss region of the EEL spectra, an apparent blue shift of;the E-2 interband transition peak up to 2 eV and a strong reduction in;the oscillator strength were measured for the NCs in the size range of;4-6 nm. It indicates for this smaller size range a transition to a QC;regime where the band structure and the density of states are modified;dramatically. These trends are explained by a combination of low-loss;and core-loss EELS results, which show that the Ge NCs are surrounded;uniformly by nearly stoichiometric SiO2. This local chemistry is shown;to provide an infinite potential barrier and to confine electrons and;holes in the spherically shaped Ge NCs. In addition to pure QC effects;in the Ge NCs, the SiO2 matrix thus plays an important role in the;strength of the observed QC and interband transitions.

For the single-chain magnet formed by the;strongly anisotropic manganese(III) acetate meso-tetraphenylporphyrin;complexes coupled to the phenylphosphinate ligands, the experimental;metamagnetic-type magnetization curve in the c direction yields an;accurate estimate of the values of correlation energy Delta(xi)/k(B) =;7.93 K and exchange coupling J/k(B) = 1.20 K.

The formulas in the existing literature are frequently;incomplete, incorrect, or lack a derivation; in particular, Hall;viscosity is overlooked. Our approach begins from the response to a;uniform external strain field, which is an active time-dependent;coordinate transformation in d space dimensions. These transformations;form the group GL(d, R) of invertible matrices, and the infinitesimal;generators are called strain generators. These enable us to express the;Kubo formula in different ways, related by Ward identities; some of;these make contact with the adiabatic transport approach. The importance;of retaining contact terms, analogous to the diamagnetic term in the;familiar Kubo formula for conductivity, is emphasized. For;Galilean-invariant systems, we derive a relation between the stress;response tensor and the conductivity tensor that is valid at all;frequencies and in both the presence and absence of a magnetic field. In;the presence of a magnetic field and at low frequency, this yields a;relation between the Hall viscosity, the q(2) part of the Hall;conductivity, the inverse compressibility (suitably defined), and the;diverging part of the shear viscosity (if any); this relation;generalizes a result found recently by others. We show that the correct;value of the Hall viscosity at zero frequency can be obtained (at least;in the absence of low-frequency bulk and shear viscosity) by assuming;that there is an orbital spin per particle that couples to a perturbing;electromagnetic field as a magnetization per particle.

L. de Andres, F. Guinea, and M. I. Katsnelson, Phys. Rev. B;86, 144103 (2012)]. Under compression, flexural modes are responsible;for a long-wavelength rippling with a large amplitude and a marked;anharmonic behavior. This is compared with corrugations created by;thermal fluctuations and the adsorption of a light impurity (hydrogen).;Typical values for the later are in the sub-Angstrom regime, while;maximum corrugations associated to bending modes quickly increase up to;a few Angstroms under a compressive stress, due to the intrinsic;instability of flexural modes.

In the PRL paper, H-CDW was defined as a new;parameter for expressing CDW chirality for the first time. In his;Comment, he claims that H-CDW is ill defined. He also claims that the;initial phase phi of the CDW wave function is a more appropriate;parameter for expressing chiral CDW, despite our early introduction of;phi to explain the experimental data described in the PRL paper.;However, we conclude that H-CDW can distinguish the CDW chirality by its;sign. Moreover, by considering different H-CDW signs, we had succeeded;in demonstrating the difference of the spatial distributions of CDWs as;shown in Fig. 4 of the PRB paper [Phys. Rev.

We show that his argument;regarding the identification of the CDW with the opposite sign of q is;wrong, since the logic is inapplicable to a wave function with a nonzero;phi. We also discuss the applicability of H-CDW to two- or;three-dimensional CDWs in transition metal dichalcogenides.

It is shown that the Dzyaloshinskii-Moriya;interactions significantly modify the triplon dispersions around the;Gamma point and cause a shift of the spin-gap (the minimum triplon gap);position from the K to Gamma point in the first Brillouin zone. The spin;gap is also evaluated in exact diagonalization studies on a 24-site;cluster.

The islands are initially placed on the;top of the pillars, in the so-called Cassie-Baxter state. For high;pillars, the dynamics is divided into two phases. The first phase;corresponds to the deterministic and irreversible impalement of the;island. The dynamics of this phase is governed by surface diffusion.;Once the island has collapsed, a second phase is observed where the;island exhibits Brownian motion along the pillars, characterized by a;diffusion constant D-i and a kinetic coefficient K-i accounting for the;interaction of the island with the top of the pillars. The random walk;stops when the island reaches the bottom of the substrate, where it;sticks irreversibly. When the island wettability is small, the island;diffusion constant D-i is controlled by adatom diffusion, and scales as;the inverse of the number of atoms in the island. In contrast, for large;wettabilities, we observe that D-i oscillates as the island size is;increased. The minimum of the oscillations corresponds to;nucleation-limited dynamics, where D-i is independent of the island;size.

We construct a low-energy effective theory by restricting the;microscopic Hamiltonian of electrons to the space of incompressible;deformations and show that the theory of the quantum Hall edge so;obtained is a generalization of a chiral conformal field theory. In our;theory, a quasiparticle tunneling operator is found to be a;single-valued function of tunneling point coordinates, and its phase;depends on the topology determined by the positions of Ohmic contacts.;We describe strong coupling of the edge states to Ohmic contacts and the;resulting quasiparticle current through the interferometer with the help;of a master equation.

Two cases are considered. The first is the;counterflowing (Vinen) turbulence, where the vortex lines are;disordered, and the evolution of quantity L(t) obeys the Vinen equation.;The second case is the fluctuations of the VLD in a single vortex;bundle, which develops inside the domain of the concentrated;normal-fluid vorticity. The dynamics of the vortex bundle is described;by the Hall-Vinen-Bekarevich-Khalatnikov (HVBK) equations. The latter;case is of special interest, because the set of the quantum vortex;bundles is believed to mimic classical hydrodynamic turbulence. In;steady states the VLD is related to the normal velocity as L = (rho;gamma/rho(s))(2)upsilon(2)(n) for the Vinen case. In the vortex bundle;case, which appears inside the domain of a concentrated vorticity of;normal fluid, the stationary quantity L can be found from the matching;of velocities and is described by L = vertical bar del x v(n)vertical;bar/kappa. In nonstationary situations, and particularly in the;fluctuating turbulent flow, there is a retardation between the;instantaneous value of the normal velocity and the quantity L. This;retardation tends to decrease in accordance with the inner dynamics,;which has a relaxation character. In both cases, the relaxation dynamics;of the VLD is related to fluctuations of the relative velocity.

Rev. Lett. 104, 255702 (2010)]. Here we examine;possible high-T, P polymorphism in Ta with complementary DFT-based model;generalized pseudopotential theory (MGPT) multi-ion interatomic;potentials, which allow accurate treatment of much larger system sizes;(up to similar to 80000 atoms). We focus on candidate bcc, A15, fcc,;hcp, and hex-omega phases for the high-T, P phase diagram to 420 GPa,;studying the mechanical and relative thermodynamic stability of these;phases for both small and large computational cells. Our MGPT potentials;fully capture the T = 0 DFT energetics of these phases, while MGPT-MD;simulations demonstrate that the higher-energy fcc, hcp, and hex-omega;structures are only mechanically stabilized at high temperature by;large, size-dependent, anharmonic vibrational effects, with the;stability of the hex-omega phase also being found to be a sensitive;function of its c/a ratio. Both two-phase and Z-method melting;techniques have been used in MGPT-MD simulations to determine relative;phase stability and its size dependence. In the large-cell limit, the;two-phase method yields accurate equilibrium melt curves for all five;phases, with bcc producing the highest melt temperatures at all;pressures and hence being the most stable phase of those considered. The;two-phase bcc melt curve is also in good agreement with dynamic;experimental data as well as with the MGPT melt curve calculated from;bcc and liquid free energies. In contrast, we find that the Z method;produces only an upper bound to the equilibrium melt curve in the;large-cell limit. For the bcc and hex-omega structures, however, this is;a close upper bound within 5% of the two-phase results, although for the;A15, fcc, and hcp structures, the Z-melt curves are 25%-35% higher in;temperature than the two-phase results. Nonetheless, the Z method has;allowed us to study melt size effects in detail. We find these effects;to be either small or modest for the cubic bcc, A15, and fcc structures,;but to have a large impact on the hexagonal hcp and hex-omega melt;curves, which are dramatically pushed above that of bcc for simulation;cells less than 150 atoms. The melt size effects are driven by and;closely correlated with similar size effects on the mechanical stability;and the vibrational anharmonicity. We further show that for the same;simulation cell sizes and choice of c/a ratio, the MGPT-MD bcc and;hex-omega melt curves are in good agreement with the QMD results, so the;QMD prediction is confirmed in the small-cell limit. But in the;large-cell limit, the MGPT-MD hex-omega melt curve is always lowered;below that of bcc for any choice of c/a, so bcc is the most stable;phase. We conclude that for the non-bcc Ta phases studied, one requires;simulation cells of at least 250-500 atoms to be free of size effects;impacting mechanical and thermodynamic phase stability.

To describe collective plasma;excitations in the 2DEG, we develop a generalized transmission line;theoretical formalism consistent with the plasma hydrodynamic model. We;then apply this formalism to analyze the plasmonic spectra of 2DEG;systems with steplike periodic changes of electron density, gate;screening, or both. We show that in a periodically modulated 2DEG, a;plasmonic crystal is formed, and we derive closed-form analytical;expressions describing its energy band spectrum for both infinite and;finite size crystals. Our results demonstrate a nonmonotonic dependence;of the plasmonic band gap width on the electron density modulation. At;so-called transparency points, where the plasmon propagates through the;periodic 2DEG in a resonant manner, the plasmonic band gaps vanish. In;semi-infinite plasmonic crystals, we demonstrate the formation of;plasmonic Tamm states and analytically derive their energy dispersion;and spatial localization. Finally, we present detailed numerical;analysis of the plasmonic band structure of a finite four-period;plasmonic crystal terminated either by an ohmic contact or by an;infinite barrier on each side. We trace the evolution of the plasmonic;band spectrum, including the Tamm states, with changing electron density;modulation and analyze the boundary conditions necessary for formation;of the Tamm states. We also analyze interaction between the Tamm states;formed at the opposite edges of the short length plasmonic crystal. The;validity of our theoretical approach was confirmed in experimental;studies of plasmonic crystals in short, modulated plasmonic cavities;[Dyer et al., Phys. Rev.

The measured 1/f;noise around the magnetic hysteresis loops of the free layer indicates;that the main origin of the 1/f noise is the magnetic fluctuation, which;is discussed in terms of a fluctuation-dissipation relation. Random;telegraph noise (RTN) is observed to be symmetrically enhanced in the;hysteresis loop with regard to the two magnetic configurations. We found;that this enhancement is caused by the fluctuation between two magnetic;states in the free layer. Although the 1/f noise is almost independent;of the magnetic configuration, the RTN is enhanced in the antiparallel;configuration. These findings indicate the presence of spin-dependent;activation of RTN. Shot noise reveals the spin-dependent coherent;tunneling process via a crystalline MgO barrier.

We have determined both the;field-current state diagrams for the domain-wall state and the thermally;activated dynamics of the nucleation and depinning processes. We show;that the nucleation process is well-described by a modified Neel-Brown;model taking into account the spin-transfer torque, whereas the;depinning process is independent of the current. This is confirmed by an;analytical calculation which shows that spin-torques have no effect on;the Arrhenius escape rate associated with thermally activated domain;wall depinning in this geometry.

In all;cases, the magnetic moments lie in the ac plane, along the CoO6;octahedra axis, at an angle of 9.3 degrees with respect to the c axis.;The magnetic structure of alpha-CoV2O6 resolved for all the ordered;states is successfully related to a theoretical model. Ab initio;calculations allowed us to (i) confirm the ground-state magnetic;structure, (ii) calculate the interactions between the Co ions, (iii);explain the frustration leading to the stepped variation of the;magnetization curves, (iv) calculate the orbital magnetic moment (1.5;mu(B)) on Co atoms, and (v) confirm the direction of the magnetic;moments near the c direction.

We also discuss the role of explicit calculation of the;Kelvin-wave interaction Hamiltonian and "symmetry arguments" that have;to resolve a contradiction between the Kozik-Svistunov and the;L'vov-Nazarenko spectrum of weak turbulence of Kelvin waves.

To describe collective plasma;excitations in the 2DEG, we develop a generalized transmission line;theoretical formalism consistent with the plasma hydrodynamic model. We;then apply this formalism to analyze the plasmonic spectra of 2DEG;systems with steplike periodic changes of electron density, gate;screening, or both. We show that in a periodically modulated 2DEG, a;plasmonic crystal is formed, and we derive closed-form analytical;expressions describing its energy band spectrum for both infinite and;finite size crystals. Our results demonstrate a nonmonotonic dependence;of the plasmonic band gap width on the electron density modulation. At;so-called transparency points, where the plasmon propagates through the;periodic 2DEG in a resonant manner, the plasmonic band gaps vanish. In;semi-infinite plasmonic crystals, we demonstrate the formation of;plasmonic Tamm states and analytically derive their energy dispersion;and spatial localization. Finally, we present detailed numerical;analysis of the plasmonic band structure of a finite four-period;plasmonic crystal terminated either by an ohmic contact or by an;infinite barrier on each side. We trace the evolution of the plasmonic;band spectrum, including the Tamm states, with changing electron density;modulation and analyze the boundary conditions necessary for formation;of the Tamm states. We also analyze interaction between the Tamm states;formed at the opposite edges of the short length plasmonic crystal. The;validity of our theoretical approach was confirmed in experimental;studies of plasmonic crystals in short, modulated plasmonic cavities;[Dyer et al., Phys. Rev.

The measured 1/f;noise around the magnetic hysteresis loops of the free layer indicates;that the main origin of the 1/f noise is the magnetic fluctuation, which;is discussed in terms of a fluctuation-dissipation relation. Random;telegraph noise (RTN) is observed to be symmetrically enhanced in the;hysteresis loop with regard to the two magnetic configurations. We found;that this enhancement is caused by the fluctuation between two magnetic;states in the free layer. Although the 1/f noise is almost independent;of the magnetic configuration, the RTN is enhanced in the antiparallel;configuration. These findings indicate the presence of spin-dependent;activation of RTN. Shot noise reveals the spin-dependent coherent;tunneling process via a crystalline MgO barrier.

Therefore inelastic;scattering processes of helical Dirac electrons become possible, as;described by a dynamical local self-energy of second order in the;exchange interaction. The self energy influences bound-state formation;and leads to significant new anomalies in the LDOS at low energies and;low temperatures, which we calculate within the T-matrix approach. We;propose that they may be used for spectroscopy of local impurity spin;states by appropriate tuning of the chemical potential and magnetic;field.

In this paper, we answer;this question for two-dimensional (2D) bosonic SPT phases with Z(N) and;U(1) symmetry. We find that while the low-energy modes of the gapless;edges are nonchiral, symmetry acts on them in a "chiral" way, i.e., acts;on the right movers and the left movers differently. This special;realization of symmetry protects the gaplessness of the otherwise;unstable edge states by prohibiting a direct scattering between the left;and right movers. Moreover, understanding of the low-energy effective;theory leads to experimental predictions about the SPT phases. In;particular, we find that all the 2D U(1) SPT phases have even integer;quantized Hall conductance.

To this end, we further develop the general,;finite-temperature real-time transport formalism by introducing field;superoperators that obey fermionic statistics. This direct second;quantization in Liouville Fock space strongly simplifies the;construction of operators and superoperators that transform irreducibly;under the Anderson-model symmetry transformations. The fermionic field;superoperators naturally arise from the univalence (fermion-parity);superselection rule of quantum mechanics for the total system of quantum;dot plus reservoirs. Expressed in these field superoperators, the causal;structure of the perturbation theory for the effective time-evolution;superoperator kernel becomes explicit. Using the constraints of the;causal structure, we construct a parametrization of the exact effective;time-evolution kernel for which we analytically find the eigenvectors;and eigenvalues in terms of a minimal set of only 30 independent;coefficients. The causal structure also implies the existence of a;fermion-parity protected eigenvector of the exact Liouvillian,;explaining a recently reported result on adiabatic driving;[Contreras-Pulido et al., Phys.

B 85, 075301 (2012)] and;generalizing it to arbitrary order in the tunnel coupling Gamma.;Furthermore, in the wide-band limit, the causal representation;exponentially reduces the number of diagrams for the time-evolution;kernel. The remaining diagrams can be identified simply by their;topology and are manifestly independent of the energy cutoff term by;term. By an exact reformulation of this series, we integrate out all;infinite-temperature effects, obtaining an expansion targeting only the;nontrivial, finite-temperature corrections, and the exactly conserved;transport current follows directly from the time-evolution kernel. From;this new series, the previously formulated RT-RG equations are obtained;naturally. We perform a complete one-plus-two-loop RG analysis at finite;voltage and magnetic field, while systematically accounting for the;dependence of all renormalized quantities on both the quantum dot and;reservoir frequencies. Using the second quantization in Liouville space;and symmetry restrictions, we obtain analytical RT-RG equations, which;can be solved numerically in an efficient way, and we extensively study;the model parameter space, excluding the Kondo regime where the;one-plus-two-loop approach is obviously invalid. The incorporated;renormalization effects result in an enhancement of the inelastic;cotunneling peak, even at a voltage similar to magnetic field similar to;tunnel coupling Gamma.

For this purpose, Ge NCs embedded in an SiO2;matrix with controllable size, density, and structure were fabricated;using magnetron sputtering. The size dependence of the Ge plasmon;energies in the size range of 5-9 nm is shown to be well depicted by the;so-called medium quantum confinement (QC) model, with an effective mass;of 0.57m(0) (contrary to expectations of a stronger quantum effect). In;the very low-loss region of the EEL spectra, an apparent blue shift of;the E-2 interband transition peak up to 2 eV and a strong reduction in;the oscillator strength were measured for the NCs in the size range of;4-6 nm. It indicates for this smaller size range a transition to a QC;regime where the band structure and the density of states are modified;dramatically. These trends are explained by a combination of low-loss;and core-loss EELS results, which show that the Ge NCs are surrounded;uniformly by nearly stoichiometric SiO2. This local chemistry is shown;to provide an infinite potential barrier and to confine electrons and;holes in the spherically shaped Ge NCs. In addition to pure QC effects;in the Ge NCs, the SiO2 matrix thus plays an important role in the;strength of the observed QC and interband transitions.

For the single-chain magnet formed by the;strongly anisotropic manganese(III) acetate meso-tetraphenylporphyrin;complexes coupled to the phenylphosphinate ligands, the experimental;metamagnetic-type magnetization curve in the c direction yields an;accurate estimate of the values of correlation energy Delta(xi)/k(B) =;7.93 K and exchange coupling J/k(B) = 1.20 K.

The formulas in the existing literature are frequently;incomplete, incorrect, or lack a derivation; in particular, Hall;viscosity is overlooked. Our approach begins from the response to a;uniform external strain field, which is an active time-dependent;coordinate transformation in d space dimensions. These transformations;form the group GL(d, R) of invertible matrices, and the infinitesimal;generators are called strain generators. These enable us to express the;Kubo formula in different ways, related by Ward identities; some of;these make contact with the adiabatic transport approach. The importance;of retaining contact terms, analogous to the diamagnetic term in the;familiar Kubo formula for conductivity, is emphasized. For;Galilean-invariant systems, we derive a relation between the stress;response tensor and the conductivity tensor that is valid at all;frequencies and in both the presence and absence of a magnetic field. In;the presence of a magnetic field and at low frequency, this yields a;relation between the Hall viscosity, the q(2) part of the Hall;conductivity, the inverse compressibility (suitably defined), and the;diverging part of the shear viscosity (if any); this relation;generalizes a result found recently by others. We show that the correct;value of the Hall viscosity at zero frequency can be obtained (at least;in the absence of low-frequency bulk and shear viscosity) by assuming;that there is an orbital spin per particle that couples to a perturbing;electromagnetic field as a magnetization per particle.

L. de Andres, F. Guinea, and M. I. Katsnelson, Phys. Rev. B;86, 144103 (2012)]. Under compression, flexural modes are responsible;for a long-wavelength rippling with a large amplitude and a marked;anharmonic behavior. This is compared with corrugations created by;thermal fluctuations and the adsorption of a light impurity (hydrogen).;Typical values for the later are in the sub-Angstrom regime, while;maximum corrugations associated to bending modes quickly increase up to;a few Angstroms under a compressive stress, due to the intrinsic;instability of flexural modes.

In the PRL paper, H-CDW was defined as a new;parameter for expressing CDW chirality for the first time. In his;Comment, he claims that H-CDW is ill defined. He also claims that the;initial phase phi of the CDW wave function is a more appropriate;parameter for expressing chiral CDW, despite our early introduction of;phi to explain the experimental data described in the PRL paper.;However, we conclude that H-CDW can distinguish the CDW chirality by its;sign. Moreover, by considering different H-CDW signs, we had succeeded;in demonstrating the difference of the spatial distributions of CDWs as;shown in Fig. 4 of the PRB paper [Phys. Rev.

We show that his argument;regarding the identification of the CDW with the opposite sign of q is;wrong, since the logic is inapplicable to a wave function with a nonzero;phi. We also discuss the applicability of H-CDW to two- or;three-dimensional CDWs in transition metal dichalcogenides.

It is shown that the Dzyaloshinskii-Moriya;interactions significantly modify the triplon dispersions around the;Gamma point and cause a shift of the spin-gap (the minimum triplon gap);position from the K to Gamma point in the first Brillouin zone. The spin;gap is also evaluated in exact diagonalization studies on a 24-site;cluster.

The islands are initially placed on the;top of the pillars, in the so-called Cassie-Baxter state. For high;pillars, the dynamics is divided into two phases. The first phase;corresponds to the deterministic and irreversible impalement of the;island. The dynamics of this phase is governed by surface diffusion.;Once the island has collapsed, a second phase is observed where the;island exhibits Brownian motion along the pillars, characterized by a;diffusion constant D-i and a kinetic coefficient K-i accounting for the;interaction of the island with the top of the pillars. The random walk;stops when the island reaches the bottom of the substrate, where it;sticks irreversibly. When the island wettability is small, the island;diffusion constant D-i is controlled by adatom diffusion, and scales as;the inverse of the number of atoms in the island. In contrast, for large;wettabilities, we observe that D-i oscillates as the island size is;increased. The minimum of the oscillations corresponds to;nucleation-limited dynamics, where D-i is independent of the island;size.

We construct a low-energy effective theory by restricting the;microscopic Hamiltonian of electrons to the space of incompressible;deformations and show that the theory of the quantum Hall edge so;obtained is a generalization of a chiral conformal field theory. In our;theory, a quasiparticle tunneling operator is found to be a;single-valued function of tunneling point coordinates, and its phase;depends on the topology determined by the positions of Ohmic contacts.;We describe strong coupling of the edge states to Ohmic contacts and the;resulting quasiparticle current through the interferometer with the help;of a master equation.

Two cases are considered. The first is the;counterflowing (Vinen) turbulence, where the vortex lines are;disordered, and the evolution of quantity L(t) obeys the Vinen equation.;The second case is the fluctuations of the VLD in a single vortex;bundle, which develops inside the domain of the concentrated;normal-fluid vorticity. The dynamics of the vortex bundle is described;by the Hall-Vinen-Bekarevich-Khalatnikov (HVBK) equations. The latter;case is of special interest, because the set of the quantum vortex;bundles is believed to mimic classical hydrodynamic turbulence. In;steady states the VLD is related to the normal velocity as L = (rho;gamma/rho(s))(2)upsilon(2)(n) for the Vinen case. In the vortex bundle;case, which appears inside the domain of a concentrated vorticity of;normal fluid, the stationary quantity L can be found from the matching;of velocities and is described by L = vertical bar del x v(n)vertical;bar/kappa. In nonstationary situations, and particularly in the;fluctuating turbulent flow, there is a retardation between the;instantaneous value of the normal velocity and the quantity L. This;retardation tends to decrease in accordance with the inner dynamics,;which has a relaxation character. In both cases, the relaxation dynamics;of the VLD is related to fluctuations of the relative velocity.

Rev. Lett. 104, 255702 (2010)]. Here we examine;possible high-T, P polymorphism in Ta with complementary DFT-based model;generalized pseudopotential theory (MGPT) multi-ion interatomic;potentials, which allow accurate treatment of much larger system sizes;(up to similar to 80000 atoms). We focus on candidate bcc, A15, fcc,;hcp, and hex-omega phases for the high-T, P phase diagram to 420 GPa,;studying the mechanical and relative thermodynamic stability of these;phases for both small and large computational cells. Our MGPT potentials;fully capture the T = 0 DFT energetics of these phases, while MGPT-MD;simulations demonstrate that the higher-energy fcc, hcp, and hex-omega;structures are only mechanically stabilized at high temperature by;large, size-dependent, anharmonic vibrational effects, with the;stability of the hex-omega phase also being found to be a sensitive;function of its c/a ratio. Both two-phase and Z-method melting;techniques have been used in MGPT-MD simulations to determine relative;phase stability and its size dependence. In the large-cell limit, the;two-phase method yields accurate equilibrium melt curves for all five;phases, with bcc producing the highest melt temperatures at all;pressures and hence being the most stable phase of those considered. The;two-phase bcc melt curve is also in good agreement with dynamic;experimental data as well as with the MGPT melt curve calculated from;bcc and liquid free energies. In contrast, we find that the Z method;produces only an upper bound to the equilibrium melt curve in the;large-cell limit. For the bcc and hex-omega structures, however, this is;a close upper bound within 5% of the two-phase results, although for the;A15, fcc, and hcp structures, the Z-melt curves are 25%-35% higher in;temperature than the two-phase results. Nonetheless, the Z method has;allowed us to study melt size effects in detail. We find these effects;to be either small or modest for the cubic bcc, A15, and fcc structures,;but to have a large impact on the hexagonal hcp and hex-omega melt;curves, which are dramatically pushed above that of bcc for simulation;cells less than 150 atoms. The melt size effects are driven by and;closely correlated with similar size effects on the mechanical stability;and the vibrational anharmonicity. We further show that for the same;simulation cell sizes and choice of c/a ratio, the MGPT-MD bcc and;hex-omega melt curves are in good agreement with the QMD results, so the;QMD prediction is confirmed in the small-cell limit. But in the;large-cell limit, the MGPT-MD hex-omega melt curve is always lowered;below that of bcc for any choice of c/a, so bcc is the most stable;phase. We conclude that for the non-bcc Ta phases studied, one requires;simulation cells of at least 250-500 atoms to be free of size effects;impacting mechanical and thermodynamic phase stability.
